Safely Dispose Of Unused Acid

How To Remove Calcium From Pool Tile (and keep it GONE!)

Contact your local pool supply business or municipality to learn how to dispose of any unused muriatic acid. Do not simply throw it away or pour it down a drain.

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

If thats your situation, you have two remaining options: a pumice stone and a lot of elbow grease, or pressure washing.

Since we already spent time on the intense nature of cleaning with muriatic acid, we will skip the pumice stone method to give you a break and talk about pressureor beadwashing.

How Do You Remove Limescale From Black Tiles

Mixing equal parts vinegar and baking soda together to form a paste supplies a mild abrasive.

Ways To Prevent Calcium Buildup In Pool

When calcium and other minerals have been dissolved in water, they tend to stick to the surfaces of your pool. This is because conditions are not met. As a result, the deposits end up creating an unpleasant effect on your skin or eyes. So it is very important that you do whatever is necessary to prevent this from happening. Here are some steps you can take:

Cover your swimming pool Try covering your pool when it is not in use. Covering your pool will keep out debris as well as sunlight which causes evaporation.

How To Defeat Calcium Scaling In Your Swimming Pool

Calcium scaling is an unsightly white to white-grey stain that forms on pool sides when a pools calcium levels and pH are imbalanced. Not to worry though, calcium scaling is an easy thing to prevent with regular water testing and balancing. In fact, how susceptible your pool is to calcium scaling is directly related to how porous your pool material is. For example, a concrete pool is the most porous, where as vinyl liner and fiberglass pools are the least.

Although it may be difficult to do, calcium scales can be removed and preventative steps can be taken to keep them from reforming. If your pool has a buildup of calcium scaling, heres how to identify what type of calcium youre dealing with, treat it and stop it from forming again.

Calcium From Cement In Coping Tiles

How To Remove Calcium From Pool Tile

Calcium can seep out through the cement that binds the top coping tiles above the vertical waterline tiles. Without doubt this is the most common cause of calcium formation in swimming pools. In this case, the calcium formation comes from the chemical reaction within the cement. This type of calcium is called calcium hydroxide and is often produced during the hydration of cement. White cement is made with around 31% calcium and this can cause calcium scale in tiles to seep out of the joints and into the pool. This calcium will often start right under the coping tiles and run downward toward the water. This type of calcium is very hard and is often quite thick in places.

Remove Efflorescence On Pool Tile And Stone:

Similar to calcium scale which comes from the pool water, efflorescence is calcium lime scale that comes from the grout between tiles or stones placed into a wall or water feature.

To remove tile scale on pools, first scrape off the heavy deposits with a small putty knife, then use a flower watering can to pour of Acid Magic or Instant Liquid Acid, full strength on the front lip of the coping, to run over the tile. Scrub the tile with a stiff brush if possible, then rinse off with a hose within 60 seconds. Repeat if needed, then raise the pool water pH and Alkalinity, now lower from the acid.

What causes this is moisture coming out from behind the tile or stone through the grout or mortar joints and bringing calcium with it. The same process that creates stalagmites.

Sometimes the moisture comes from the pool as shown below. Sealers can be used on the tile to provide an invisible barrier. For larger stone or brick walls above the water, preventing efflorescence may require sealing or redirecting the source of water behind the wall.

Why Is There Calcium On My Tiles And Why Is It So Urgent To Remove It

To put simply, calcium is a mineral that has many important functions in our bodies and throughout nature. It is a normal part of life. Since calcium is in the water we drink, that also means it is in the water that fills your pool. As the water level in your pool rises and lowers, tiny water droplets containing calcium atoms will be left on the side of the tiles and lining. When the water evaporates, the calcium is left behind and sticks to the side of your pool.

1. Regular buildup from hard water

Calcium deposits are either uniform in distribution, like on the pool liner at water level, or they aggregate in certain spots. Perhaps you have a fountain that always runs off in a certain spot over time, an aggregate of calcium will form which spreads like wildfire, leaving you with a thick, dense deposit of calcium.

The calcium deposit will grow faster and faster as time goes on, leaving you to scramble to fix it before it becomes unmanageable.

2. Your pool is too alkaline

When your pools pH is too basic , this speeds up the scale release from the water and buildup occurs at a faster rate. Getting your pool to optimal pH can slow the process, but reverse it or eliminate it entirely.

What Is Calcium Hardness

Youve heard of hard water, right? You may live in an area where the municipal water is hard. Or you may even get your water from a well. Either way, it means your water supply has a high level of minerals, including calcium.

But wait, calciums a good thing, isnt it? It makes strong, healthy bones and teeth. Sure, thats true. But its not so good for your pool and all the expensive equipment you bought to keep it clean and healthy.

Over time, an out-of-whack calcium hardness level can do some real damage, which is why its so important to monitor and balance the calcium hardness in your pool.

What Causes Limescale Buildup

Before cleaning your pool surfaces free from calcium deposits, you need to understand what causes the white stains on your pool tile.

The most common cause of calcium buildup is from a high pH level or alkalinity, which causes calcium carbonate to separate from the pool water and leave an unwanted stain.

Another potential cause of limescale buildup is intense heat. High temperatures evaporate water quickly and are more likely to leave a calcium stain behind. Any pool surfaces that come in contact with water are at risk for calcium scaling.

    Why Does Calcium Build Up In Salt Cells

    HEAT The hotter the water, the more calcium tends to drop out of pool chemical solutions and mineralize into a deposit. Since the cell plates generate heat, they tend to build scale after many uses. This is also why calcium often builds around pool heaters. High pH pH is a by-product from the generator converting salt into chlorine .

    Reduce Hardness In Pool Water

    As with every other aspect of water chemistry, calcium hardness also needs to be in balance to protect your pool surface from calcium formation, stains, or corrosion. Unlike pH and chlorine, the calcium level in most pools does not vary greatly over the seasons, so testing every few months is normally enough. Importantly, high or low calcium hardness can cause white staining on pool surfaces, etching, or discolouration. Remember, the trick is to keep the calcium at the right level and to keep the water balanced. If everyone did this then there would be no calcium buildup in pool surfaces at all.

    FAQ- Calcium Hardness

    What level should my calcium be?

    For pebble, quartz and glass bead pools the suggested calcium hardness is 200-250ppm. Suggested levels for fibreglass pools vary depending on the manufacturer?

    Does high calcium cause calcium spots ?

    As a rule, there is no link between calcium levels and calcium buildup in pool interiors. Calcium stains and spots are usually caused from poor water balance.

    Do calcium Hardness reducers work ?

    In our experience, calcium hardness reducers do reduce calcium levels in the short term. However, over time the calcium hardness returns to the old levels.

    does calcium effect water quality ?

    Calcium rich water is called hard water. This is because the calcium content is very high. Low calcium water is called soft water which feels much nicer to swim in.
