Calcium Deposit

 

Cal­cium scal­ing is that nasty white film that forms around the water lines of your beau­ti­ful swim­ming pool. Not only is it unat­trac­tive; cal­cium buildup may also indi­cate some thing’s off in your water chem­istry balance.

Here are a few ways to pre­vent and remove cal­cium buildup:

1. Address the Chemistry

Deposits will begin to form when cal­cium lev­els are too high. Test your pool reg­u­larly to ensure that cal­cium hard­ness lev­els are between approx­i­mately 200–400 parts per mil­lion. You can lower cal­cium lev­els by dilu­tion (drain­ing a por­tion of the pool and refill­ing it with fresh water) or use a spe­cial prod­uct designed for that purpose.

Main­tain­ing proper pH (7.4 to 7.6 ppm is ideal) and alka­lin­ity (80 to 100 ppm) will also pre­vent scal­ing. You can lower cal­cium lev­els through dilu­tion (drain­ing a por­tion of the pool and refill­ing it with fresh water) or through the use of com­mer­cially avail­able seques­ter­ing agents.

 

2. Get Out Your Brush

 Brush­ing your pool walls needs to be included in your rou­tine pool main­te­nance. This helps pre­vent future cal­cium buildup.

 

3. Use Spe­cial For­mu­las on the Deposits

You can apply a solu­tion of muri­atic acid diluted with water directly to the cal­cium deposits, then give the area a good brush­ing. The solu­tion is applied with a sponge or sprayed onto the deposits. Don’t for­get to test your water chem­istry after­wards; acid can lower the pH.

 

4. Big Guns for Stub­born Cal­cium Buildup

Spe­cial­ized pool main­te­nace tech­ni­cians can remove deposits by using a scraper like a putty knife or “blast­ing” using sand, glass beads or some other soft media. The blast­ing tech­nique is effec­tive, but expensive.
