Description
The Zodiac Calcium Up commonly known as “hardness increaser” is added to the water to help protect the finish of your swimming pool or spa finish. Too much calcium and it will scale on the finish and too little the water will pull it from the surface. Calcium requirements change depending on which finish you have and it is always best to contact the manufacturer of your finish to find the ideal calcium level.
- Essential for water balance
- Helps protect pool surfaces and equipment
