What You Should Know About Pool Cleaning: Pool pH, Filtration, and Pool Maintenance

Cleaning your pool can be a hassle if you don’t have the right guidance to go about it. Thankfully, we brought together the main highlights of pool maintenance and prepared this to guide you. We’ll talk about your pool pH and managing and also how to handle your pool filtration. We added a checklist to guide you on your Saturday pool cleaning.

Swimming Pool pH Balance

The water in your swimming pool contains an extremely complex balancing system. When we talk about water balance in a swimming pool, we are referring to 3 parameters: pH – TAC (alkalinity) – TH (limestone).

Focus primarily on pH. It should be between 7.2 and 7.4. You measure it with an electronic pH meter, strips, or liquid tests.

The pH should be checked at least once a week (or even twice a week, or even every day in the event of exceptional climatic conditions). And correct it if necessary with pH less or pH more.

Note: The pH conditions the effectiveness of treatment products, in particular, that of chlorine. Too high a ph strongly harms the action of chlorine.

A poorly balanced pH is very often the cause of swimming pool water problems (cloudy, green, etc.).

If you often have pH problems, you will need to go a little further in the analysis and control the TAC and TH.

Easy cleaning of the pool

Filtration and disinfection (associated with a good water balance) are the essential steps in the routine maintenance of the swimming pool. Now we have to clean the pool in order to maintain our hydraulic circuit and our pond.

Filtration cleaning

Filtration consists of the swimming pool water renewal circuit. The main players are the pump which sets the water in motion and the filter which will clean the pool water. All of this is connected by pipelines. The skimmer sucks in the water and the delivery nozzles return the previously filtered water.

It is therefore important:

  • To have a filter and a pump adapted to the volume of water in your swimming pool (to be determined with a professional)
  • To filter your water on a daily basis and to regulate the filtration time efficiently (never “under-filter”)
  • To clean its filtration regularly

If these settings are ok, you will save yourself a lot of trouble.

Regarding the filtration time, think about the rule:

Filtration time = water temperature divided by 2

Water problems are often caused by an under-filtered pool.

Also, be careful: Do not filter your pool at night. It must be filtered during the day when UV rays are most active.

Consider helping your filtration. In order for it to run smoothly, you must avoid asking it indiscriminately. You should also monitor the level of clogging of the filter and clean it as necessary. For a filter to clean properly, the filter load must still be clean.

When your pool is too dirty, clean it with your vacuum cleaner by putting the water directly into the sewer so as not to require filtration unnecessarily.

The use of an electric swimming pool robot makes it possible not to put too much strain on the filtration of the swimming pool (autonomous robot not connected to the filtration circuit of the swimming pool).

Remember to regularly empty the skimmer baskets and the pump prefilter. This will help your filtration to run optimally.

Tip: There are socks or pre-filters that you can put on your skimmer baskets. This limits the clogging of the filter.

Monitor the filter pressure via the pressure gauge (which gives you an indication of the level of clogging of the filter). It is necessary to clean its filter very frequently.

For sand filters, a backwash (or backwash) + rinsing is carried out in order to clean the filter material which retains all the impurities.

You will then send water to the sewer. You will then need to refill your pool with new water. Rely on the turbidity indicator to determine the duration of the backwash. When the water becomes clear again, you can stop. And above all, think about rinsing (a very often forgotten step).

Pool surveillance

Every day, take a quick look at your pool and the general water quality. The faster you act, the easier and faster the corrective action will be.

Also, check the water level in your pool. It must never go below half of the skimmers (optimal level = ¾ top of the skimmers). Otherwise, you will suck air into your hydraulic circuit.

It is also important to renew your water regularly, this will allow you to avoid many problems (at least 1/3 of the total volume of water every year).

The Saturday Check List: For Easy Maintenance of your pool

I advise you to choose a “pool maintenance” day during the week, it will be easier to use. Saturday is generally a good day because it marks the start of the weekend.

I give you a list of weekly tasks (knowing that some tasks can be bi-weekly, even daily, depending on weather conditions).

Clean the pool with a landing net and a vacuum cleaner or robot

  • Scrub the walls and clean the waterline
  • Empty the pump pre-filter and the skimmer baskets
  • Backwash + rinse the sand filter
  • Check the water level and refill the pool if necessary
  • Check the level of disinfectant / Disinfect your pool with your usual product
  • Check the pH and correct it if necessary (pH less or pH more)
  • Control the water temperature and adjust your filtration time if necessary

Normally, the maintenance of a swimming pool does not take more than 30 minutes per week.

Note: Following a thunderstorm or heavy rains, check your water well. Indeed, the storm deteriorates the quality of the water more quickly. The hotter it is, the more vigilant you have to be and regularly check the water.

In Summary

The comfort of your swimming pool depends on good organization. The goal of the game is to do some corrective actions in order to avoid a big curative action, long, expensive, and… irritating!

You can also get help from automatic devices (electrolyzer, auto regulator, chlorinator, etc.). Once installed and configured, they bring you a certain comfort. It will still be necessary to ensure the proper functioning of these devices.

Happy swimming!

How a Calcium Releaser Can Help You Remove Calcium Deposits in Your Pool

“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.

How to Remove Lime Deposits

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.

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.

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.


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 Clean the Tough Heavy Calcium Deposits in Your Pool

Tags : 

Calcium deposits, or efflorescence, form when excess moisture inside cement rises to the surface. These white powder deposits are common in basement walls, floors, and other cement surfaces.

Although efflorescence is not harmful to cement, excessive amounts of it can cause fungal or insect problems. Once the calcium deposits harden, they are virtually impossible to remove without acid solutions.

Stronger acids are required for the heavier calcium deposits.


  1. Dress appropriately for security purposes. Wear protective clothing, goggles, acid-resistant gloves, and a mask equipped with an acid-grade filter.
  2. Set a portable fan nearby and open the windows to provide adequate air circulation. Fill a spray bottle with acetic acid.
  3. Spray the acetic acid generously on the calcium deposits. Allow the acid to penetrate the cement for the recommended amount of time. Follow the manufacturer’s instructions on the product label.
  4. Scrub the cement with a hard bristle brush to dissolve the calcium deposits. Continue to apply acetic acid and scrub the cement until all calcium deposits are removed.
  5. Sprinkle baking soda generously over clean cement to neutralize the acid. While the acid neutralizes, fill a plastic bucket with water.6 Clean the affected surfaces promptly to restore the appearance of the cement and prevent future problems. To do this, cement thoroughly rinsed with water, using a coarse sponge. Allow the cement to air dry.

Tips and warnings

  • You can substitute hydrochloric acid for acetic acid. However, never use hydrochloric acid inside or mix it with any chemical.
  • Be very careful when using acetic acid; It is highly corrosive to the skin.

Cleaning with vinegar

Baking soda, borax, dish soap, toothpaste, and vinegar can be used in much the same way to clean calcium deposits, so you can use most of the information related to the vinegar and apply it also to cleaning agents.

What you need for cleaning with vinegar:

  • A cleaning brush. With soft bristles, not metallic.
  • A bottle of spray.
  • Vinegar, a 5% solution.

Once you have these items, you can start cleaning.

  1. The first step is to stop all use of the pool until a water test can be performed. If the test reveals that the levels are within range, you can use a stain remover to remove deposits from the waterline. If the pH, alkalinity or calcium levels are too high, they should be reduced before using a scale and scale cleaner.
  2. It is recommended to start first by lowering the hardness of the water. The hardness can only be lowered by partially draining and then filling the pool. Your pool needs a hardness level of 200 ppm to 400 ppm. A level of hardness above 400 ppm can lead to scale formation on the surface of the pool and equipment and can also cause cloudy water.
  3. Once the pool has drained, and filled again, check that the hardness is within range. If it is not, you must repeat step 2 until you normalize the hardness. Only in that case can you adjust the alkalinity. You should retest before doing so because the alkalinity should be lower than before. To reduce alkalinity, you can use dry acid or muriatic acid. The necessary amount of any of the chemical products will vary according to the size and volume of the pool and the reading of alkalinity.
  4. Once the alkalinity is within the range, the pH can be adjusted. For this, a negative pH is used, in case of a high pH. Once the pH is balanced, we can move on to the final step.
  5. The final step will be to use the vinegar. Before adding the product, (following the package instructions), make sure you have a pool brush handy to brush the walls as needed. There are no special tricks. You can put the vinegar in the bottle and spray the solution on the calcium deposits or simply pour it from your own bottle, then use the brush to scrub.

These types of cleaners tend to work quite well if you detect and solve the problem from the beginning, and of course, you should use them fairly regularly to avoid accumulation.

If you do all these steps, and still have lime deposits that are difficult to remove, try the following.

Cleaning with muriatic acid

With the vinegar and the other mild cleansers that we have already mentioned, you can enter the pool while you are cleaning. With muriatic acid, however, this is not recommended.

Muriatic acid is more powerful and more dangerous when handling. You can find this chemical in a home improvement store or pool supply store.

What you need for cleaning with muriatic acid:

  • Muriatic acid container.
  • Safety glasses.
  • Rubber gloves.
  • Respirator.
  • Plastic cube.
  • Measuring cup of plastic.
  • Plastic spoon
  • Plastic spray bottle.
  • Marker.
  • Non-abrasive scourer

This list of materials is enough for you to realize that this goes beyond the maintenance of the pool for beginners. We want to remind you that muriatic acid is dangerous.

  1. Put on goggles, gloves, and the respirator. Then head outside with all your ingredients to start mixing. Absolutely do not attempt to mix in a closed area.
  2. Fill your bucket with four liters of water. Pour 230 grams of muriatic acid with the measuring cup slowly into the water. Always pour the acid in the water instead of the other way round, as the acid is more likely to splash. Another thing to keep in mind is that you should pour slowly since this mixture produces heat.
  3. With the plastic spoon, mix the water and the acid. Again, do it slowly, because you do not want it to boil.
  4. Carefully fill the plastic bottle with a mixture of water and acid.
  5. Use the marker to label the measuring cup, spoon and spray bottle with “Muriatic acid”. Do not try to use the chemical for anything else. If you are worried that this may happen, leave the bottle aside for proper disposal.
  6. You should always stay out of the pool, use the spray bottle to spray the waterline of the pool and rub with the non-abrasive scouring pad.

Get in touch with your local pool supply company or with the municipality to learn how to get rid of any unused muriatic acid. Do not simply discard it or pour it down the drain.

Because muriatic acid is much stronger than vinegar or other cleaning products mentioned above, you can eliminate calcium deposits that are much more advanced. That said, with deposits that have been growing and hardening for a long time, sometimes even muriatic acid is not enough.

If that is your situation, you have a remaining option. Pressure washing.

Everything You Need to Know About Your Pool pH Level

Tags : 

A lot of people have questions regarding the pH levels of their pools. The significance of your pool’s pH level stretches from personal health to pool hygiene. In this article, we help you answer some of the questions you have on your mind.

How to raise the pool pH

How to raise the pH of your pool? Do you need to increase your pool’s pH levels? How to raise the pH in a pool is the question we ask ourselves if in our periodic or punctual measurement a significant variation of pH is detected.

In this case, you must immediately use pH boosters or reducers, as appropriate. If the pH is low or acidic, use a pH Booster to raise water ph. If you do not know how to raise the pH of the pool water then we present the products that will solve the problem of how to raise the pool pH.

From now on, how to increase the pool pH will be the easiest problem to solve the summer.

If you need to know how to increase the pH of the pool, we have selected the best products on the market to raise the pool and that the boring task of increasing the pool is a simple task for you. Contact us.

How to lower the pool pH

How do you lower pH pool?

If the pH is high or basic (alkaline), use a pH Reducer. It is very important that this product addition is done gradually and waits a while, usually, a few hours are enough, to re-measure the pH of our pool. The pool filter needs to be in operation for the pH corrector distribution to be done effectively and spread throughout the pool’s water volume.

If we maintain the pH levels of the water in our pool correctly, we can enjoy water in perfect conditions, making the rest of our pool additives such as flocculants, algaecides, and chlorine itself works properly. Therefore, knowing how to lower pH+ pool is an important matter to control.

What are the Ideal pH Levels for Your Pool?

The pH is one of the most important measures and parameters to maintain the water quality of your pool. If you keep the pH at the right levels, in addition to enjoying healthy water you can keep the water in your pool clean and crystal clear.

The pH is the measure of the acidity or basicity of a solution, in this case, the water in our pool. The optimal values recommended by the experts range between 7.2 and 7.6, so we must pay attention and be alert if the average obtained falls outside the indicated range.

If the pH decreases below 7.2 we have acidic water. If this happens, it will cause irritation to the skin, eyes, and mucous membranes, in addition to generating corrosion problems in the pool materials (metal ladders, pumps, valves, and filters).

If on the contrary, the pH value rises above 7.6, the water in our pool becomes basic or alkaline. As was the case with acidic water, alkaline water, in addition to previous symptoms such as skin and eye irritation, would also cause dryness in our skin. Due to the basicity of the water, traces of calcium compounds are generated on the surface of the pool, and consequently, the water is seen in a more turbid and less crystalline form, also reducing the desired sterilizing and disinfectant effect with the addition of chlorine, consequently generating algae problems.

Experts recommend that periodic checks be made to maintain good water quality, as well as to maintain pH levels at levels suitable for bathing. It is advisable to perform a pH measurement at least once a week, acting as explained below if the pH parameters are beyond the ranges indicated.

Importance of the pH of the Pool

Why Does it Rise and Fall?

The ideal pH range for our pool water to be healthy ranges from 7.2 to 7.6, but sometimes when we take the measurement with our pH meter we are surprised that this value has risen or fallen.

The reasons why the pool’s ph rises (or falls) are mixed and varied, but commonly the pH of the pools usually gives high values, that is, basic ph’s:

  1. A determining factor has to do with the amount of water in the pool. Weather factors such as wind and sun make the water evaporate over time and therefore the pH increases as the amount of water decreases. On the other hand, ultraviolet radiation from the sun increases the dissolution rate of chlorine in water, generating a gradual increase in pH values.
  2. A second factor is the bathers themselves. The sunscreens, moisturizers, body lotions, hair cells, dead skin, and even electrolytes from sweat make both chlorine and water acidity to be modified. Generally, bathers also cause pH levels to rise.
  3. Finally, the way to add chlorine to the pool can also change the pH values. The chlorine added in liquid form is nothing more than sodium hypochlorite, that is, bleach. This salt in the form of a solution is a highly alkaline or basic substance and therefore its addition generates significant pH increases. Chlorine added in tablets, on the other hand, includes trichloroisocyanuric acid that acidifies the water, thus reducing the pH of the water. A third modality is a form of granulated chlorine, which is characterized by having a pH close to neutrality (6.7) and the pH levels will be close to 7 therefore.

If for some reason you add more chlorine than you should, you should know how to lower the chlorine of the pool. For this, there are different techniques we will discuss later.

How to keep the pH at optimal values?

Maintaining the pH value at optimal values ​​is of the utmost importance. Failure to do so creates a danger to the health of the users of the pool. The recommended pH values ​​range between 7.2 and 7.6, so a periodic pH measurement is advisable. Broadly speaking, when the pH becomes acidic and falls below 7.2, acidic water can irritate the eyes and skin (it is important to know how to increase the pool). If the pH rises from 7.6 becoming the basic water, there is a loss of effectiveness of the dissolved chlorine and therefore a decrease of the disinfectant power that is pursued.

The pH meter or pH meter is the scientific instrument specially designed for these tasks. In the market, we have different types of meters, such as digital, pocket, and even the test strips, which although they give us semiquantitative values, we must not neglect their effectiveness, simplicity, and ease of use.

Expert recommendations tell us that pH measurements must be made periodically or after special episodes, such as a storm. The rain and the pollution that drags in its precipitation tend to acidify the water and raise the pH.

It is also advisable to measure it after the use of the pool by a large number of bathers since the use of lotions, sun creams, and the bathers’ own sweat can cause the pH to rise and become more basic.

With this, you understand your pool’s pH better. And you can make better decisions to enjoy your pool to the maximum.
