BioGuard Zero Phos : Product Information

BioGuard Zero Phos is a powerful and effective high level phosphate remover. Using this product will drop your phosphate levels to near zero in just 24 hours. Ideally your phosphate level should be zero, but whether your level is at 500 ppb to over 2,000 ppb, this product will help reduce it. Phosphates can get into your pool from source water, consistent bad weather, and ground runoff. No matter the source, BioGuard Zero Phos is a necessary product to get your phosphate level back under control.
