Natural Chemistry Phosfree 3L

Reducing phosphate levels in pools is easy with Natural Chemistry's patented Phosfree​ technology. Phosfree​ is formulated from lanthanum (rare earth) compounds. When added to the skimmer, a thin coating of Phosfree​ forms on the filter media. As pool water flows through the filter, phosphates are reduced to a very low level.

Directions:

1. Clean or backwash filter.
2. Determine the appropriate dose. * See chart below.
3. Shake the bottle well before application. With the circulation pump running, add a dose to the skimmer.
4. Run the filter for 48 hours continuously without backwashing or cleaning.
5. After 48 hours of filtering, clean/backwash filter. Retest phosphate levels, and if necessary, repeat steps 1-5.
