Filtrite Dry Acid (pH Down)

Filtrite Dry Acid prevents itchy skin, scaling of pool equipment, cloudy pools and surfaces. This will lower elevated pH levels from new plaster surfaces, algae and some pool chemicals and increases sanitizer efficiency. It contains Sodium Bisulphate which is safer than pool acid. Use as needed to achieve a suitable range of 7.2 to 7.6 to keep your water swim-ready and clear. Dry Acid is an ideal, safe alternative to liquid pool acid. Application: To decrease the total alkalinity by 10ppm in 25,000 litres
