Easy to use and fast dissolving, it precisely adjusts alkalinity by 10 ppm per 11 ounces per 5,000 gallons, ensuring a balanced, crystal-clear pool environment.

## Description

This product raises the total alkalinity in swimming pool water. It boosts the effectiveness of your pool water disinfectant, as well as aids in the prevention of scale formation, metal corrosion and the etching of pool surfaces. It helps maintain your pool’s pH level and eliminates pH “bounce”. Easy to use and dissolves quickly. Test for total alkalinity with a reliable test kit. The desired range for total alkalinity is as follows: Fiberglass Pools 70-100 ppm, Marcite, Painted, Tile, or Exposed Aggregate Pools 80-120 ppm, Vinyl Pools 120-140 ppm. If the total alkalinity is less than this desired range, add this product directly to the pool water while the pump is in operation, in accordance with the included table.
