APPLICATION
To reduce Phosphates by 750ppb add 32 oz per 10,000 gallons of pool water. For a 375ppb reduction add 16 oz per 10,000 gallons.
NOTE
Double recommended dose when opening or closing the pool for the season or if bather loading increases significantly. Apply product more frequently (i.e. half the dose, twice per week) to arrive at the same weekly rate of product consumption. Performance will improve with more frequent application. Use automated pump if possible. Apply when water temperature is 50-110ºF and pH and alkalinity are at recommended levels.
IMPORTANT
Do not mix directly with sanitizers or other chemicals. Safe to swim immediately after use.
