Most effective way to remove phosphates!

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.

- Shake bottle well prior to application. With circulation pump running, add dose to simmer.

- Run filter for 48 hours continuously without backwashing or cleaning.

- After 48 hours of filtering, clean | backwash filter. Retest phosphate levels, and if necessary, repeat steps 1-5. 

Note: If DE filter pressure rises to 10psi above start-up pressure, turn pump off for 1 minute and then turn it back on. If pressure remains high, backwash or rinse for 30 seconds.

For DE & Cartridge Filters:​ Do not add more than 1.5L (48oz) at a time. If more than 1.5L (48oz) is needed to treat, be sure to clean or backwash the filter between treatments.

Important:​ Algae must be treated prior to testing and lowering phosphates. Chlorine must be under 5ppm before testing phosphates.
