Description
BioGuard Zero Phos is designed to remove phosphates from your pool water. It adds a fine layer of compounds to the surface of your filter that reduces the number of phosphates in your pool as water passes through it. Phosphates are what various types of algae eat, so a high phosphate level makes it easier for algae to grow in the pool. Phosphate levels should be 500ppb or less.
Available size: 946mL
How to Use Zero Phos:
- Backwash your sand filter or ensure your cartridge filter is clean before adding Zero Phos
