Spa Choice Increase Calcium increases the calcium hardness in spas and hot tubs. The ideal calcium level for spas is between 200-400 parts per million. When calcium levels are too low, spa water can be foamy and corrosive to equipment. When calcium levels are too high, you will see scale formation on the spa's interior and the water will become cloudy. Use a test kit or test strip to test your spa calcium levels. This product is used to increase calcium hardness in spas and hot tubs in areas with low levels of hardness. Low hardness will etch plaster and corrode equipment. Before adding this product, test the water with a calcium hardness test kit or ask your local spa dealer. The ideal hardness level is 200-400 ppm (parts per million). DIRECTIONS: 1 ounce of product per 500 gallons increases hardness by about 10 ppm. 1. Determine amount of product to be added using a calcium hardness test kit. 2. Pour proper amount into spa or hot tub with equipment turned ON. 3. Run filter for 1-2 hours. 4. Water may be retested in 20 minutes.
