ClearSpa pH Plus is a pH increaser to be used as necessary when the pH is below 7.2 in swimming pool and spa water.
For optimal results, maintain swimming pool pH levels on a weekly basis. Mix product with water in a 5-gallon bucket before adding to pool (8 - 10 ounces to 1 gallon of water). For large adjustments, split the recommended dose into 3 individual treatments (1 treatment per day). Evenly distribute the recommended dose around the perimeter of the pool, primarily in the deep end. Turn on pool equipment and allow to circulate for a minimum of 8 hours. Brush pool floor and steps to mix any undissolved product. See packaging label for complete instructions and follow manufacturer directions for use. Wear personal protective equipment (PPE) as directed.
