Phosfree is one of the most effective ways to remove phosphates in your water. Phosphates are the building block for algae growth.
Reducing phosphate levels in pools is easy with Natural Chemistry’s patented Phosfreetechnology. 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.
*Please read all labels before adding any chemical to your pool, follow all safety instructions and consult a pool professional if you have any questions.
2L & 3L
Directions For Use:
This product is designed for use in properly balanced pool water.
1. Clean or backwash filter
2. Determine appropriate dose. (See guidelines 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.
If your current Phospate level is:
300 ppb or less, add 0.5L or 16oz
600 ppb, add 1L or 32oz
900 ppb, add 1.5L or 48oz
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.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. Algae must be treated prior to testing and lowering phosphates. Chlorine must be under 5ppm before testing phosphates.
