5 Simple Ways to Remove Calcium Deposits From Pool Quickly

Tags : 

Have you noticed some greyish white scales in your pool? Or some discoloration right around the water line in your pool? Or even some crusty deposits in the corner of your pool? If yes, those are calcium deposits.

What are Calcium Deposits in the Pool?

Calcium carbonate is a chemical compound made up of a carbonate ion and a calcium ion. It is the main constituent of limestone. This is because limestone is a combination of calcium carbonate and magnesium carbonate.

Calcium carbonate can settle in your pool and form whitish and possibly rough deposits. The effects of limestone are negative for your swimming pool: scaling, deterioration of equipment, cloudy water, etc. Lime deposits in a swimming pool can also promote the development of algae on the walls.

Depending on where you live, the water contains more or less calcium carbonate. Before filling your pool, measure the hardness of the filling water. This will allow you to select the right treatment products, but also to choose the suitable swimming pool filter, because some clog and scale more easily than others (the diatomaceous filter in particular).

Removing Calcium Deposits From Your Pool

This must be one of the many questions on the mind of a pool owner.I would be giving 5 ways on how to remove calcium deposits from your pool.

1. Use a calcium releaser

These products makes it easy to remove calcium deposits. While selecting your product, select acid free calcium releasers, as these products are left a long time on your pool tile before scrubbing off, and the acid could destroy your pool finish.

2. Use scaling treatment

If your pool is made of fiber glass, scaling treatment is advised because other methods would scratch the glass since they involve brushing.

3. Use a pumice

This rock is also effective in removing calcium deposits in pools, make sure the surface of both the rock and the pool is wet, and do not scrub too hard in order not to deface your pool.

4. Use white vinegar and a scrub brush

Fill a water bottle spray with half water and half vinegar solution, spray on your pool tile and leave for some minutes before rubbing gently with a scrub brush.

5. Use muriatic acid

This is also known as Hydrochloric acid, this acid has high strength in removing mineral deposits, calcium deposits inclusive.While using it, you should be fully clothed with your google and gloves in order to avoid safety hazards. Make sure not to leave the acid too long because you do not want to destroy the finish of your pool.

Bottomline

You can always try:

Calcium deposits are caused by an imbalance between the calcium levels and the Ph of your pool.Before we go into removing these calcium deposits, to prevent future deposits you might want to do the following:

(1) Try reducing evaporation in your pool, by installing a pool cover, because when water evaporates, calcium becomes concentrated.

(2) Try draining your pool and lowering the PH of the new water, this is done so if the pool is exposed to sunlight, there won’t be an imbalance between the PH and the calcium level.

Calcium deposits in pools can have side effects on people who use the pool, these effects can range from eye irritation to whole body irritation, they are also irritating to look at and would reduce the interest of people in your pool.

When removing these deposits, make sure you are dressed properly to avoid safety hazards and also try as much as possible not to destroy the finish of your pool.

With this guide, we are sure you will bring your pool to its former glory.

6. Clean the edge of the pool regularly

Cleaning the edge of the pool is a tedious task that is often postponed. However, we recommend that you regularly clean the edge of your pool.

You will thus eliminate the lime at the height of the waterline. If you put off this task over and over, you will have a hard time removing the scale deposit.

Therefore, take the time to meticulously clean the edge of your pool on a regular basis. You will thus obtain an impeccable water line, without the slightest trace of lime on the interior coating.

7. Add fresh water regularly

Our last tip should only apply a few times a year. Adding new water to the pool reduces certain concentrations of salts and metals, such as chlorides, iron, copper, etc.

These concentrations must be reduced in order to guarantee good disinfection of the swimming pool water. In addition, high concentrations of metals can cause brown spots to appear in the pool.

To avoid this inconvenience, add 3 to 5% of the total water volume in your pool at least 3 times a year. Warning: do not use well water in particular. This indeed contains too high concentrations of these metals. You could therefore make the situation worse.

How to Get Rid of Lime Deposits from Well Water in Your Pool

Tags : 

When calcium forms on your pool, an effect known as limescale, your pool can look unsightly and even be in danger.

If lime develops in your pool, you should hire pool maintenance professionals to inspect and clean up debris from its surfaces. Most pool cleaning services make a diagnosis for the localization and the elimination of limescale.

If you want to do it yourself, read the rest of the article.

How to detect lime deposits in your Pool

Look for white or light gray spots on the sides and bottom of the pool, as well as the edges of the pool deck. Limestone forms scaly spots or streaks when the pH of the pool water and the calcium levels in the water are out of balance.

Although this build-up of lime can be removed, it can be difficult to do so. This article provides homeowners with tips that any pool maintenance company wouldn’t want you to know to remove lime deposits from the pool walls and prevent their return.

Lime stains in the pool

If you have ever noticed, you will have seen that there is a white line on the walls, at the height of the surface. This is caused by lime deposits.

In pools with well water, these lime deposits form in a short time, and if they are not removed, the layer becomes thicker and difficult to clean.

Another problem is the roughness that is noticeable on the walls, when passing the hand the touch is rough.

Over time, this texture favors the accumulation of dirt and makes cleaning more difficult.

In addition, if you apply acid to dilute the lime, you are also diluting the cement in the joints, damaging the lining, until you have to empty the pool to repair it.

What if you use well water for your pool?

On many occasions, especially in pools installed in rural areas, there is no access to running water, so there is no choice but to use well water to fill the pool.

Well, I have a trick to remove lime from the pool with well water.

Well water treatment

This trick is not for everyone. It is not difficult to apply, but you have to be careful to follow the steps correctly.

If the pool is already affected by the remains of lime, you should lower the pH as much as possible, adding a lot of acid, or liquid pH-.

With a pH lower than 6, the lime will start to thin, but so will the cement joints.

It is VERY IMPORTANT that no one takes a bath during the process. The acidity of the water will be very aggressive for people.

After a few days in this state, empty the pool completely, clean the surfaces well with acid (better to use a specific liquid or pH reducer based on sulfuric acid, because hydrochloric acid or sulfonate emits a lot of vapors). Finally, you will have to re-grout (apply Borada or seal with cement) all the joints.

As you can see, it is slow and hard work, and it is better to do it out of season, to avoid the effects of heat on the empty pool.

With the pool empty, the next step is filling (you probably already guessed that).

Start filling it by adding shock bleach.

The well water contains a lot of organic matter, is very “alive”, and then the plant matter, such as algae, begin to react to the light of the sun. Water can go bad in a matter of hours. Sometimes the same water is already green. Don’t worry about adding more chlorine than necessary, while no one takes a bath.

How to purify well water

Now comes the secret.

Add flocculant to the water. Yes, it’s that easy, but wait, this is just the beginning.

The flocculant causes all elements other than water to stick together, forming solid “flakes” (flocs) that settle to the bottom of the pool or remain stuck in the sand filter.

Be very careful not to overdo the dose of flocculant, because the sand can stick, and you will have to replace it.

calcium removal calcium killer

You will have to do sand washes every few hours so that the sediment is expelled.

These remains will include lime, algae, metals, and other elements.
The water will be practically pure. You will also have to help by sweeping the bottom so that the dirt does not stay there.

You can increase the effectiveness by adding a layer of diatomaceous earth, or diatomaceous sand over the filter sand, to retain a greater amount of debris.

Anyway, think that diatomite is difficult to find and somewhat expensive, so it is not necessary to use it unless you want to do a cleaning worthy of an operating room.

Most of it will go down the drain when doing a sand wash, so this is disposable.

The process time will depend on the type of water you are treating, so you will have to experiment and observe.

You can also repeat the process after a few days. However, it is better to do it before adding salt, in salt chlorination systems.

Types of Calcium that Leave Deposits

There are 2 common types of calcium that form lime in a pool: calcium carbonate and calcium silicate. It is important to understand which type harms the walls of your pool.

The calcium carbonate is white, scaly and easily detached. Calcium silicate is slightly gray and more solid, which makes it more difficult to remove.

If the walls of your pool contain calcium silicate, the scale on the walls of your pool is a symptom of a more serious problem: calcium scale in the plumbing and filtration system. This is a problem that only a professional pool maintenance company can deal with.

If you don’t know what type you have on your pool, use a dropper to pour muriatic acid on the deposits. Calcium carbonate will foam in reaction to acids. Calcium silicate, being a more solid substance with robust construction, will remain unchanged.

Removing Calcium Carbonate

If your pool contains calcium carbonate, removing it is easy, but takes time.

You can use a rough but harmless object for tiles such as a wet pumice stone or an eraser to flake off deposits.

You can also get calcium descaling treatment solutions from a pool service company or a pool supply store. Follow the product instructions to avoid damaging the pool water or injuring yourself.

Removal of Calcium Silicate

Calcium silicate is incredibly difficult to remove on your own. You can try using a pumice stone, but it will take a ton of elbow grease and time to complete the process successfully.

If you have a vinyl or fiberglass pool, this will not work at all. Even some descaling treatments can take months to break down the lasting calcium silicate.

You will probably need to hire pool maintenance professionals to remove lime build-up if you cannot do it yourself. They can also adjust the quality of your pool water, including pH and calcium levels, to prevent future buildup.

Remove limestone with a blowtorch and a polishing machine

If you have emptied your pool to clean it and you notice traces of lime, there are two methods that can get rid of this debris. These methods are effective but can take a long time depending on the size of your pool.

To remove the lime that is in the walls of your pool, just use a blowtorch to make the tartar less robust and then rub it with a wire brush. With the effect of heat, the tartar will be easily removed.

If you have limestone at the bottom of the pool, simply clean the pool thoroughly with a vacuum cleaner, then sand it with a sanding and polishing machine.

Once descaling and polishing are finished, rinse your pool with a karcher to remove debris. Then evacuate your pool, let it dry, and fill it again if you want to reuse it.

If you do not want to fill it immediately, choose a tarpaulin or a protective cover. Your pool will therefore remain intact and ready to be filled at any time you wish.

Good to know

The disadvantage of chlorine is that it makes no difference between organic impurities and the human body. The consequences after a long stay in the water are red eyes, caused by chlorine. This is the reason why most people wear swimming goggles.

Why and How to Remove Limescale From Pool Heater and Swimming Pool

Tags : 

Calcium deposits are formed on surfaces that touch hard water. Even though these deposits occur naturally, they can cost you a lot of money if you do not eliminate them. Calcium deposits can cause a water heater to increase fuel use by 40 percent or more. It is beneficial to observe these deposits and withdrawals when possible.

Measure the amount of lime in swimming pool water

Measuring the level of lime in the water in your swimming pool is in fact the same as measuring the hardness of the water, always given in TH (hydrometric strength). Very easily carried out thanks to bands with colorimetric indicators, this test will make it possible to determine the concentration of calcium and magnesium carbonate (and therefore of limestone) in the water in our basin.

Generally speaking, it is estimated that the ideal TH for swimming pool water should be between 10 ° f and 20 ° f. Beyond 20 ° f, the east is said to be hard. And above 25 ° f, it is considered that its lime concentration is too high: it must therefore be treated with an anti-lime product.

Why is having lime in your swimming pool a problem?

If pool owners hunt limestone like this, it’s not for nothing. Having excess lime in your swimming pool can indeed be the cause of various problems.

First of all, at the level of the interior of the basin. Because the more our pool is loaded with limestone, the more “chance” we have of seeing it build up from the inside. 

And this as well at the level of the waterline as at the level of the walls and the bottom (especially if one has opted for a swimming pool liner as a coating). And a scaled pool is a pool whose water will be cloudy, and whose walls will be covered with gray or whitish deposits.

Stains which, in addition to being unsightly, will promote the appearance of ‘impurities and algae development. Without forgetting the possible inconvenience for swimmers: possible irritation of the skin and eyes.

But that’s not all: having too much lime can also be dangerous for the filtration system of the swimming pool. Indeed, when there is too much lime in our water, it will simply build up scale and prevent the proper functioning of the swimming pool filter.

Instructions to remove large calcium deposits from water heater

  1. Drain all water from the water heater tank.
  2. Remove the drain valve. With a wrench, unscrew the valve.
  3. Insert a long, narrow brush through space from which you have removed the drain valve. Rub each inside surface of the bottom of the tank with the brush.
  4. Reinstall the drain valve. Apply Teflon tape on the outside of the valve to prevent leaks.
  5. Open the drain valve and attach a garden hose to it.
  6. Open the water supply through the hose and in the water heater. Leave on for 15 to 20 seconds and then turn it off.
  7. Let all the water drain out of the tank.
  8. Repeat this filling and draining process until the water draining from the stove is clear.

How to prevent limescale in the swimming pool

If you live in an area where the water is hard (TH greater than 20), the limestone will represent a real danger for our pool and our equipment. To avoid having to change our liner or completely empty our pool to scrub the limestone from the walls, it is better to act upstream.

To do this, we can:

  • Buy a lime stabilizer from a pool equipment store to prevent lime deposits in the pool.
  • Check that the pool water is not too hot, as a high temperature favors the formation of scale.
  • Carry out at least 3 anti-limescale treatments per year. The first to commissioning the pool, the next in mid-season, and finally the last before putting the pool in winter. Obviously, if our pool shows signs of scaling outside of these 3 periods, we apply an anti-limescale treatment and we rub the walls well.

Is Calcium Building Up On the Waterline of Your Pool?

Tags : 

Lime stains in pool

A common issue that every pool owner will encounter at some point down the road would be calcium buildup in the area around the pool. Calcium buildup can cause your pool to look dated and aged. You spend tens and thousands on a new pool why not just keep it that way? We see so many pools in which the owner didn’t control it! But not everyone knows until it happens to them!

The waterline is the usual residue point

The waterline is the most common area for calcium and lime to build up. It’s very important to address it at first sight so it can’t become a big deal because as these build up it causes damage to your pool whether you see it or not. It gets in the pool filters that are designed for soft objects, not hard calcium. See how this can be a potential issue? Another common thing that will happen if it is left untreated for too long is that it will continue to damage the plaster and grow. This will grow anyplace near the pool that is constantly wet. Now that leaves you with 2 problems to fix because the first wasn’t addressed when it should have been!

Is calcium deposits irritating your eyes?

A lot of people enjoy swimming with their eyes open and not with goggles. When it gets to a certain point calcium deposit can start to just appear in the pool. This leaves the swimmers at risk of opening their eyes underwater. Another thing is that it leaves the pool uncomfortable. Leaving particles in the pool and making it uncomfortable for swimmers, causing debris to get into the eyes

Getting rid of calcium deposits

You can very easily take care of this and save yourself some money by grabbing yourself some toothpaste, baking soda, and vinegar. Using knees together and scraping off the calcium deposits can be much help. Another thing you can do is clean it with muriatic acid. This is a lot more powerful and should be handled with extreme caution. You can pick up muriatic acid at just about any pool store. But before you do any of this, contact your local pool store and tell them your situation. See if they can offer any advice on what would best help you in the end.

“How to get rid of calcium deposits in your pool”

This must be one of the many questions on the mind of a pool owner.

And here I will be giving 5 ways on how to remove calcium deposits from your pool! And not only will it look better, but it will also allow you to enjoy your pool like you once did!

1. Use a calcium releaser

These products make it easy to remove calcium deposits. While selecting your product, select acid-free calcium releasers, as these products are left a long time on your pool tile before scrubbing off, and the acid could destroy your pool finish.

Be careful when using these products. Even though it says “acid-free”, it still contains substances that aren’t great for the human skin or lungs. Make sure to wear protective equipment when working with calcium releasers in removing calcium deposits in your pool.

2. Use scaling treatment

If your pool is made of fiber glass, scaling treatment is advised because other methods would scratch the glass since they involve brushing.

3. Use a pumice

This rock is also effective in removing calcium deposits in pools, make sure the surface of both the rock and the pool is wet, and do not scrub too hard in order not to deface your pool.

4. Use white vinegar and a scrub brush

Fill a water bottle spray with half water and half vinegar solution, spray on your pool tile and leave for some minutes before rubbing gently with a scrub brush.

5. Use muriatic acid

This is also known as Hydrochloric acid, this acid has high strength in removing mineral deposits, calcium deposits inclusive.While using it, you should be fully clothed with your google and gloves in order to avoid safety hazards. Make sure not to leave the acid too long because you do not want to destroy the finish of your pool.

To remove the lime that is in the walls of your pool, just use a blowtorch to make the tartar less robust and then rub it with a wire brush. With the effect of heat, the tartar will be easily removed.

If you have limestone at the bottom of the pool, simply clean the pool thoroughly with a vacuum cleaner, then sand it with a sanding and polishing machine.

Once descaling and polishing are finished, rinse your pool with a karcher to remove debris. Then evacuate your pool, let it dry, and fill it again if you want to reuse it.

If you do not want to fill it immediately, choose a tarpaulin or a protective cover. Your pool will therefore remain intact and ready to be filled at any time you wish.

Good to know

The disadvantage of chlorine is that it makes no difference between organic impurities and the human body. The consequences after a long stay in the water are red eyes, caused by chlorine. This is the reason why most people wear swimming goggles.

Bottomline

Calcium deposits in pools can have side effects on people who use the pool, these effects can range from eye irritation to whole body irritation, they are also irritating to look at and would reduce the interest of people in your pool.

When removing these deposits, make sure you are dressed properly to avoid safety hazards and also try as much as possible not to destroy the finish of your pool.

How to Use Well Water for Swimming Pools: Trick to Purify It

Tags : 

When you want to install a salt chlorinator in a pool with well water, we recommend that you empty it and fill it with water from the water supply grid.

What are the drawbacks of well water

The reason is that lime and other minerals often cause problems in the chlorinator electrode.

During electrolysis, lime and other elements precipitate and end up being embedded in the plates of the chlorinator cell.

The performance of the electrode decreases, because the plates are electrically isolated, due to the layer of lime, which acts as an insulator.
To clean the electrode plates, the electrode must be immersed in acid, which also attacks metal.

After many washes, the electrode ends up having serious corrosion problems.

In addition, there are other salts and metals present in well water that cause other problems, both due to the sediments they cause and due to the electrochemical effects that are produced.

Lime stains in the pool

If you have ever noticed, you will have seen that there is a white line on the walls, at the height of the surface. This is caused by lime deposits.

In pools with well water, these lime deposits form in a short time, and if they are not removed, the layer becomes thicker and difficult to clean.
Another problem is the roughness that is noticeable on the walls, when passing the hand the touch is rough.

Over time, this texture favors the accumulation of dirt and makes cleaning more difficult.

In addition, if you apply acid to dilute the lime, you are also diluting the cement in the joints, damaging the lining, until you have to empty the pool to repair it.

How to use well water for the pool

On many occasions, especially in pools installed in rural areas, there is no access to running water, so there is no choice but to use well water to fill the pool.

Well, I have a trick to remove lime from the pool with well water.

Well water treatment

This trick is not for everyone. It is not difficult to apply, but you have to be careful to follow the steps correctly.

If the pool is already affected by the remains of lime, you should lower the pH as much as possible, adding a lot of acid, or liquid pH-.

With a pH lower than 6, the lime will start to thin, but so will the cement joints.

It is VERY IMPORTANT that no one takes a bath during the process. The acidity of the water will be very aggressive for people.

After a few days in this state, empty the pool completely, clean the surfaces well with acid (better to use a specific liquid or pH reducer based on sulfuric acid, because hydrochloric acid or sulfonate emits a lot of vapors).
Finally, you will have to re-grout (apply Borada or seal with cement) all the joints.

As you can see, it is slow and hard work, and it is better to do it out of season, to avoid the effects of heat on the empty pool.

With the pool empty, the next step is filling (you probably already guessed that).

Start filling it by adding shock bleach.

The well water contains a lot of organic matter, is very “alive”, and then the plant matter, such as algae, begin to react to the light of the sun. Water can go bad in a matter of hours. Sometimes the same water is already green. Don’t worry about adding more chlorine than necessary, while no one takes a bath.

How to purify well water

Now comes the secret.

Add flocculant to the water. Yes, it’s that easy, but wait, this is just the beginning.

The flocculant causes all elements other than water to stick together, forming solid “flakes” (flocs) that settle to the bottom of the pool or remain stuck in the sand filter.

Be very careful not to overdo the dose of flocculant, because the sand can stick, and you will have to replace it.

You will have to do sand washes every few hours so that the sediment is expelled.

These remains will include lime, algae, metals, and other elements.
The water will be practically pure. You will also have to help by sweeping the bottom so that the dirt does not stay there.

You can increase the effectiveness by adding a layer of diatomaceous earth, or diatomaceous sand over the filter sand, to retain a greater amount of debris.

Anyway, think that diatomite is difficult to find and somewhat expensive, so it is not necessary to use it unless you want to do a cleaning worthy of an operating room.

Most of it will go down the drain when doing a sand wash, so this is disposable.

The process time will depend on the type of water you are treating, so you will have to experiment and observe.

You can also repeat the process after a few days. However, it is better to do it before adding salt, in salt chlorination systems.

Prevent stains on the pool tile

I am not a fan of adding chemicals to the water, so once the pool is filled with purified water, I would try to avoid adding other products. For that, it is important that the chlorine level and the pH are perfect. There is nothing else to do.

When adding water, after washing, or simply to compensate for evaporation, we must bear in mind that we have also added lime, so we can repeat the process from time to time.

It should be done as a shock treatment. We do not recommend using maintenance flocculant, because it is still a chemical product which in large quantities is unhealthy, as you can see in this post.

If you’ve done enough washes to remove most of the lime, you’ll see that the water is crystal clear and the walls shiny.

Run your hand over the walls periodically, to make sure that the touch is smooth (but not slippery, which would be a sign of algae formation).
If you notice that they become rough, you should lower the pH a little and do another anti-limescale treatment.

Try to have these treatments done on the days that the pool is not used, to avoid exposure to bathers, especially with low pH.

Use of anti-scale products for swimming pools

There are products that keep lime in suspension, so they don’t really remove it, they just keep it from sticking to the walls.

This is an ineffective solution because it forces you to continually add chemical products, with the risks that they entail, and it also does not completely prevent lime from becoming embedded in the chlorinator electrodes.

The flocculant and sand wash trick works better, because you’re actually getting a lot of the lime out of the pool.

Other options to reduce pool limescale

In facilities with intensive use, such as spas and hotels, a tank can be installed to flocculate the water before adding it to the pool. In addition, filters or osmosis systems can be installed, which can purify the water, leaving it almost as if it were distilled.

These systems are not justified in domestic swimming pools, because with good flocculation the water quality is already very good.

How to Remove Lime Deposits From Your Pool

Tags : 

When it comes to your body, calcium is a very good thing, but when it comes to your pool, it is not. When calcium forms on your pool, an effect known as limescale, your pool can look unsightly and even be in danger.

If lime develops in your pool, you should hire pool maintenance professionals to inspect and clean up debris from its surfaces. Most pool cleaning services make a diagnosis for the localization as well as the elimination of limescale.

If you want to do it yourself, read the rest of the article.

So how do you know if your pool contains limestone?

Look for white or light gray spots on the sides and bottom of the pool, as well as the edges of the pool deck. Limestone forms scaly spots or streaks when the pH of the pool water and the calcium levels in the water are out of balance.

Although this build-up of lime can be removed, it can be difficult to do so. This article provides homeowners with tips that any pool maintenance company wouldn’t want you to know to remove lime deposits from the pool walls and prevent their return.

Types of Calcium that Leave Deposits

There are 2 common types of calcium that form lime in a pool: calcium carbonate and calcium silicate . It is important to understand which type harms the walls of your pool .

The calcium carbonate is white, scaly and easily detached. Calcium silicate is slightly gray and more solid, which makes it more difficult to remove.

If the walls of your pool contain calcium silicate, the scale on the walls of your pool is a symptom of a more serious problem: calcium scale in the plumbing and filtration system. This is a problem that only a professional pool maintenance company can deal with.

If you don’t know what type you have on your pool , use a dropper to pour muriatic acid on the deposits. Calcium carbonate will foam in reaction to acids. Calcium silicate, being a more solid substance with a robust construction, will remain unchanged.

Removing Calcium Carbonate

If your pool contains calcium carbonate, removing it is easy, but takes time.

You can use a rough but harmless object for tiles such as a wet pumice stone or an eraser to flake off deposits.

You can also get calcium descaling treatment solutions from a pool service company or a pool supply store. Follow the product instructions to avoid damaging the pool water or injuring yourself.

Removal of Calcium Silicate

Calcium silicate is incredibly difficult to remove on your own. You can try using a pumice stone, but it will take a ton of elbow grease and time to complete the process successfully.

If you have a vinyl or fiberglass pool , this will not work at all. Even some descaling treatments can take months to break down the lasting calcium silicate.

You will likely need to hire pool maintenance professionals to remove lime build-up if you cannot do it yourself. They can also adjust the quality of your pool water, including pH and calcium levels, to prevent future buildup.

Remove limestone with a blowtorch and a polishing machine

If you have emptied your pool to clean it and you notice traces of lime, there are two methods that can get rid of this debris. These methods are effective but can take a long time depending on the size of your pool.

Lime Deposits: How Chlorine Helps You in Regular Pool Treatment

Tags : 

Clean, healthy pool water should be the ultimate goal for any pool owner. The most common solution to achieve this is a regular treatment of the pool water to remove lime and debris.

Ceramic tile with a heavy build up

However, the wrong dosage of cleaning products can lead to the accumulation of several layers of limestone on the walls and in the pool’s bottom. To remove this debris, you need to understand everything that can make them appear.

The Importance of Chlorine for the Pool

Chlorine is the first choice for maintaining healthy pool water. Chlorine has been used for years in swimming pools around the world.

It is a highly reactive chemical that reacts with all kinds of biological impurities in water.

If these organic impurities are not treated with care, bacteria can develop algae or even a bio-film.

What Happens if a Swimming Pool is not Well-balanced?

If the pool water has a high calcium hardness or other debris, this can cause technical problems. Like fouling or lime in the pipes and in the pool itself.

As a result, the maintenance and cleaning of the pool will increase. If the supply water is very hard, large amounts of lime can deposit on the sides of the pool.

Even if there is only a little calcium carbonate in the water, and following an unbalanced addition of chlorine and PH, lime will form at the level of the evaporation line of the water as well as on the pool walls. These lime deposits at the edge of the pool are often difficult to remove and involve manual work.

Water Filtration Rings: Less Effort, Less Cost

Compared to the maintenance consequences described above, the solutions seem incredibly simple.

The main configuration of a swimming pool is always the same. There is a filter system, a pump, and maybe a heating element, that’s all.

In accordance with the size of the pool, you must install a ring at the freshwater supply line and another ring in the circulation line. In the case of a large public swimming pool, install in the circulation line of each swimming pool, to get the same results in all swimming pools.

What’s the result?

In case of calcium hardness, the ring keeps the dissolved calcium in the pool water, which will have a more fluid texture. Over time, the pool water will be much softer, despite the calcium.

Less crust will form on the evaporation line. And limestone debris will be much easier to remove. When you use these filters and rings, you are also fighting the growth of algae in the pool.

Many owners have stopped using chemicals since the installation of these rings.

No chlorine or other pool chemicals. Without having problems with water quality.

I would not recommend such a thing for a public pool. If countless visitors use this pool, the risk would be too great. I am sure the regulatory authorities would not agree.

However, it is preferable to use these rings even for public swimming pools in order to reduce maintenance costs for protecting pipes or walls of the swimming pool. By doing this, you will need a lot less chlorine to disinfect the water than before while maintaining the same quality of water.

In the next blog post, we will talk about how lime deposits form on your pool tiles and several ways you can get rid of the problem.
