Product Description

Natural Chemistry Spa PHOSfree contains revolutionary technology specificially engineered for spas and hot tubs. When added to your spa or hot tub skimmer, a thin coating of PHOSfree forms on the filter media and as water flows through the filter, phosphates are reduced to near zero levels. Adding Spa PHOSfree at start-up and on a weekly basis reduces and maintains phosphate levels to near zero.
