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:

1. Backwash your sand filter or ensure your cartridge filter is clean before adding Zero Phos
2. Add Zero Phos to skimmer basket according to the table below:
   

   Phosphate Reading	501-1000ppb	1001-2000ppb	Over 2000ppb
   Amount needed per 38,000L	120mL	240mL	946mL*

   *If you add more than 475mL/38,000L, pool may become cloudy

3. Run pump continuously for at least 48 hours
4. If your phosphate levels were over 1000, get a phosphate test at our store to check your new phosphate levels

Tips for Using Zero Phos

• Zero Phos cannot be added at the same time as Optimizer Plus, Clarifying Tablets, or a granular stabilizer, like Stabilizer 100. Wait 3 days after adding these products to use Zero Phos
• Zero Phos will make your pool cloudy if it is added directly to the pool and not the skimmer basket
• Zero Phos should not be added if there is live algae in the pool
