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.
- Most effective way to remove phosphates prior to using a weekly maintenance product
- Works in the filter (no clouding of the pool water)
- Reduces phosphates down to near zero
- Reduces pool maintenance
- No Phosphates - No Problem
Directions for use:
This product is designed for use in properly balanced pool water.
- Clean or backwash filter.
- Determine appropriate dose. * See chart below.
- Shake bottle well prior to application. With circulation pump running, add dose to skimmer.
- 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.
Dose per 10,000 gallons (38,000L)
|Phosphate Level||PHOSfree Dosage|
|300ppb or less||0.5L or 16oz|
|600ppb||1L or 32oz|
|900ppb||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.
Important: Algae must be treated prior to testing and lowering phosphates. Chlorine must be under 5ppm before testing phosphates.Printable version

Natural Chemistry pioneered the use of phosphate removal technology long before it was popular. High phosphate levels in pool water can create many water issues. Most people today are aware of the efforts by government agencies to limit the use of phosphates in common household products due to their effect on water. Natural Chemistry has a variety of phosphate removal products that have been proven to make water care easier.
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
