Description

Natural Chemistry 05121 Phosfree 3 Liters is the most effective way to remove phosphates prior to using a weekly maintenance product. Reducing phosphate levels in pools is easy with the patented Phosfree technology of Natural Chemistry. This technology is formulated from lanthanum (rare earth) compounds. This product is designed for use in properly balanced pool water and when you add it 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. It clearly helps in reducing the levels of phosphates down to near zero as well as reduces pool maintenance. Using this for DE and Cartridge Filters, never add more than 1.5L (48oz) at a time and if more than 1.5L (48oz) is needed to treat, be sure to clean or backwash the filter between treatments. It is also recommended that algae must be treated prior to testing and lowering phosphates. Chlorine must be under 5ppm before testing phosphates. This product is in a 3-liter size.

  • Most effective way to remove phosphates
  • Works in the filter (no clouding of the pool water)
  • Reduces phosphates down to near zero
  • Reduces pool maintenance

"Got the navy version and the compartments keep everything organized. Brought it camping and it held up fine. The strap is a little long for me, easy enough to adjust. I'm in Fresno, CA. Exactly what I needed."
