What is the Whitish Deposit on Your Pool Tiles?
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. When exposed to water, calcium carbonate can sometimes form a whitish deposit, which is commonly seen as scale buildup in pipes or on surfaces exposed to hard water.
Calcium carbonate can settle in your pool and form whitish deposit 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). If your water has high hardness, it may also result in a whitish deposit on the surfaces of the pool over time, which can affect its appearance and performance.

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 how to remove calcium deposits from your pool. One common issue pool owners face is the appearance of a whitish deposit on pool surfaces, which is often caused by calcium buildup. These deposits can make your pool look unappealing and may even damage the tiles over time.
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. Additionally, if you notice a whitish deposit forming on your pool tiles, it’s a sign of calcium buildup that needs to be addressed promptly.
2. Use scaling treatment
If your pool is made of fiberglass, scaling treatment is advised because other methods would scratch the glass since they involve brushing. Over time, you may notice a whitish deposit forming on the surface, which is a sign of scale buildup. Proper scaling treatment helps prevent this issue and keeps your fiberglass pool in top condition.
3. Use a pumice
This rock is also effective in removing whitish deposit and calcium deposits in pools, making 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, whitish deposit, calcium deposits inclusive. While using it, you should be fully clothed with your goggles 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.
In Summary…
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.
Frequently Asked Questions
Why does a whitish deposit form in my pool?
A whitish deposit forms in pools due to an imbalance between calcium levels and pH. As water evaporates, calcium concentration increases, leading to the formation of stubborn deposits on pool tiles, especially around the waterline.
How do I remove the whitish deposit from my pool tiles?
You can remove the whitish deposit using several methods:
-
Calcium releasers (acid-free solutions) to break down deposits
-
Scaling treatment for fiberglass pools to prevent scratches
-
Pumice stones to scrub off deposits (ensure surfaces are wet)
-
White vinegar and scrub brush for mild buildup
-
Muriatic acid for stubborn whitish deposits (use with caution and proper protective gear)
Can the whitish deposit in my pool cause damage?
Yes, if left untreated, the whitish deposit can lead to tile discoloration, rough surfaces, and even damage to pool equipment. It may also create an ideal environment for algae growth, further affecting your pool’s cleanliness.
How can I prevent a whitish deposit from forming in my pool?
To prevent whitish deposits, you should:
-
Maintain proper pH and calcium levels
-
Use a pool cover to reduce evaporation
-
Periodically drain and refill your pool with balanced water
-
Regularly clean and brush pool tiles to prevent buildup
Is the whitish deposit in my pool harmful to swimmers?
While the whitish deposit itself isn’t toxic, it can cause irritation. Swimmers may experience eye and skin irritation if calcium levels are too high. Additionally, excessive buildup can make pool surfaces rough, leading to minor abrasions.
