Puri-Cal NSF Grade Calcite 0.55 cubic foot
PURI-CAL brand calcite is a premium grade pure NSF-Certified calcite produced in the North Cascades Mountains of Washington State. 400 million years ago, the calcite skeletons of tiny sea creatures called coccoliths collected on the ocean floors.
Over time, continual collisions and folding of the earth's crust, generating extreme pressure and temperature transformed these skeletal deposits into the high grade, pure white marble from which Puri-Cal is made. It is specially selected and sized to optimally adjust pH in potable water systems. When used in accordance with standard water treatment practices it will gently and effectively adjust the pH of your water and help minimize corrosion problems in plumbing and appliances.
- Proper use of PURI-CAL can help water systems comply with the EPA lead and copper rule.
- When used in back-washing filter systems PURI-CAL can significantly clarify cloudy and turbid water.
- PURI-CAL Independently tested and certified by NSF to Standard 60.
- Sold in 1/2 cubic foot (45 lb) bags.
- Mesh size is 16 x 40.
Note - our standard non-NSF calcite is a very clean and excellent quality calcite. Puri-Cal is NSF certified for potable water and costs more, and is used where NSF certification is required, or customers want a premimum grade. Both work well to correct low pH.
