High power phosphate removal.
PHOSfree is available in Extra Strength! It is the only patented product that removes phosphates from the filter. This extra strength formula quickly reduces extremely high phosphate levels. PHOSfree Commercial Strength offers professional service companies a great tool to reduce the time spent trying to reliably reduce very high phosphate levels. It will also work well on large commercial and institutional pools.
- Works on both the filter and in the pool for maximum phosphate removal
- Easily maintains low phosphate levels in larger volumes of water
- The most powerful formula available on the market.
Instructions for use:
1. Clean or backwash the filter
2. Apply the appropriate dose. See the table below
3. Shake the bottle well and, with the filter pump running, add the dose directly into the skimmer.

Dosage table
Phosphate Level Dosage Per Gallon
1000ppb 1/2 L 10,000 gallons
2000ppb 1 L 10,000 gallons
1000ppb 1 L 20,000 gallons
2000ppb 2L 20,000 gallons
* Do not add more than 1.5 L (50 oz or half a bottle) at a time
*To treat higher phosphate levels, add 1.5 L (50 oz or half a bottle) every 24 hours until desired result is achieved
Note : Retest the water after each treatment. Repeat until the phosphate level is below 100 ppb.
Important: Algae must be treated prior to testing and reducing phosphates. Chlorine must be below 5 ppm before testing for phosphates.
Warranty Coverage: Natural Chemistry chemicals are backed by a 30-day limited manufacturer warranty.
