In The Swim - Calcium Hardness Increaser
In The Swim’s calcium hardness increaser contains calcium chloride and comes in granular form which is fast acting and easy to use. When your pool test strip shows you pool’s hardness level has dropped below 150 ppm, simply add about six pounds per 10,000 gallons of water to raise the level by about 50 ppm.
This product can expose you to Bromate (when used in aqueous formulations with a chemical oxidizer such as ozone) which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov.
