Phos out traps dissolved phosphates in the filter, by making visible clusters large enough to be trapped in the filter. Orthophosphates are a plant nutrient and promotes algae growth. This concentrated formula is safe for use with all pool surfaces and compatible with saltwater systems.
• One PHOS OUT tablet is sufficient to reduce phosphate levels by up to 1,800 ppb in 10,000 L of pool water.
• Note: This product is not an algaecide, and treatment should be followed up with an algaecide. We recommend using GREEN OUT.
