Description
This Crystal Quest cartridge blends calcite (calcium carbonate) with coconut shell granular activated carbon. The calcite dissolves into acidic water to raise pH, while the carbon polishes taste and odor, including chlorine taste.
Highlights
- Calcite raises the pH of low pH or acidic water and dissolves more as acidity rises
- Adds calcium to low-mineral or very soft water
- Coconut shell GAC polishing stage improves taste and odor, including chlorine taste
- Four sizes from 0.5 to 6 GPM with capacities from 3,000 to 18,000 gallons
- Fits standard 2.5" x 10", 2.5" x 20", 5" x 10" and 5" x 20" housings

- Calcite is consumed as it dissolves, and some hardness increase is expected
- Output pH is not fixed and depends on incoming water, mineral content and flow
- The carbon is a polishing stage, not a full carbon stage
- Not designed to treat bacteria, viruses, fluoride, nitrate, lead or other heavy metals, iron, or high VOC or chloramine loads
- Not intended for neutral or alkaline water or microbiologically unsafe water
- Replace sooner if taste, odor, flow or pressure changes
