PhosFree Extra Strength Is The Number One Phosphate Removal Formula!

PhosFree Extra Strength by Natural Chemistry is specifically designed for high level phosphate removal. This treatment allows you to easily maintain low levels of phosphates in even the largest volumes of water.

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. PhosFree Extra Strength is a top phosphate removal formula trusted by the experts.

This product is designed for use in properly balanced pool water. Algae must be treated prior to testing and treating phosphates. Chlorine must be under 5ppm before testing for phosphates. We encourage you to retest your water after each completed treatment. Repeat the steps below until your phosphate level is below 100ppb.

Directions For Use:

  • Clean or backwash filter. Make sure DE filters are properly cleaned and charged with DE before adding product.
  • For phosphate levels over 1000ppb, add 32oz (1L) per 10,000 gallons. Do not add more than 48oz. (1.5L) at a time.
