10" calcite Remineralisation cartridge designed to fit industry standard big blue housings. These cartridges are designed for low pH water (under pH 6.0 usually) where water needs to be raised to neutral or even alkaline conditions. Calcite media, which is added or dosed to the product water, essentially 're-hardens' the supply, adding calcium back into the water.
Cartridge life: Life proportional to usage, flow and input pH
Designed to fit all regular 10" Big Blue Housings
