Calcium Chloride helps prevent corrosion of exposed metal, plaster. tile grout in pool water that lacks specific mineral content. most water seeks minerals to achieve a mineral balance. this product satisfies this need.

 

What Is the Correct Calcium Hardness Level?

If you have a concrete or plaster pool, keep the level between 200 ppm and 275 ppm.

 

If your pool has a vinyl or fiberglass liner, the calcium hardness level should be between 175 parts per million (ppm) and 225 ppm.

 

 

What is Calcium Hardness?
Calcium hardness is the measure of how hard or soft your pool water is, and measures the amount of dissolved calcium and magnesium in your swimming pool. Just like pH and total alkalinity, it’s important to keep the calcium hardness balanced to prevent your pool water from becoming corrosive or scaling. However, before you attempt to balance your pools calcium hardness level, first make sure your pools total alkalinity level is balanced, then the pH and lastly calcium hardness. 

 

Low Calcium Hardness

When pool water becomes too soft (i.e. its calcium hardness drops below 150 ppm) it becomes corrosive. If you don’t manually add calcium or magnesium back into the pool, the water will begin to take what it needs from any part of your pool or pool equipment that contains them such as stone, concrete, metal, grout, etc. Problems often associated with low calcium hardness include:

  • Eroding of tile grouting and delaminating of plaster surfaces
  • Etching or pitting of pool decks or stone and concrete surfaces surrounding your pool Corrosion of metal parts (i.e. pipes, ladders, filters, screws, etc.)
  • Pitting of concrete pool flooring and walls

Once damage from soft water occurs, there’s no way to undo it. The only way to fix the damage done by soft water is to replace or resurface the damaged part, so it’s imperative not to let your pools calcium hardness dip too far below 150ppm.

 

How to Raise Calcium Hardness in Your Swimming Pool?
If your pools calcium hardness level drops below the recommended 150 ppm the easiest and most common way to raise swimming pool calcium hardness is by adding a calcium hardness increaser such as calcium chloride to your swimming pool.

 

High Calcium Hardness

Similarly to when the pools pH level is too high, when a pools calcium hardness level is too high it becomes basic and over saturated with dissolved particles including calcium. Over time, the pool water will become cloudy and the excess amount of dissolved particles in the pool will cause the water to scale in and around your pool equipment, possibly clogging and blocking the flow of water in and out of the pool, which can damage your pool equipment.

 

How to Lower Calcium Hardness in Your Swimming Pool?
There is really only one way to lower your pools high calcium hardness level and that is to partially or completely drain your hard pool water and replace it with fresh water.
