Important information

Directions

Turn on pumps so water can circulate. Test pH level with proper pH strips. If the pH is higher than 7.8 for spas or the pH is not in the correct range for pools, add the product and allow water to circulate for several hours. Repeat until the pH is in the correct range of 7.2-7.8 for both spas and pools. For spas, pre-dissolve the product in water before adding it. The recommended dosage for pools is 1-2 pounds per 10,000 gallons of water.
