Poly-phosphate Recharge Kit
Add Poly-Phosphate every 8-12 months
By adding Poly-Phosphate to your Hard Water Filter, you ensure that the filter is delivering its best performance by sequestering the aragonite and not allowing it to build up on surfaces or create water spotting. After draining the filters housing, un-screw the filter bottom and remove the red cap on the filter which will allow for re-filling
Pour 10.5oz of poly-phosphate crystals (5 oz for the black model) into the filter as shown, use a small funnel of container. (Please refer to the attached manual above)
Poly-Phosphate crystals are a plant based FDA approved crystal that dissolve in the water slowly and sequester the calcium and aragonite causing it to stay in suspension which allows the hardness to move on downstream. Also know as Siliphos or Phosphate Silica, Poly-Phosphate has been used for many years with excellent results in the treatment of hard water in municipality’s, commercial buildings and residential applications.
