Phosfree®

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.

The phosphate test kit now included with the bottle of PHOSfree is outstanding! I now know the initial amount of chemical to be added to the pool based on test results. I am a die hard user of PHOSfree.Gerald Anglin

Phosfree® Instructions

Directions for use:

This product is designed for use in properly balanced pool water.

  1. Clean or backwash filter.
  2. Determine appropriate dose. * See chart below.
  3. Shake bottle well prior to application. With circulation pump running, add dose to skimmer.
  4. Run 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.

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.
