Other sizes available upon request.

Useful for increasing the calcium level together with KH in approximately the same   ratio    used  in
calcification by corals and coralline algae (used with FEV Alkalinity Part B).

Instructions: Add 5 mL (one capful) per 5 gallons of aquarium water to increase the calcium 10 ppm. Add slowly to a high flow area, preferably in a sump. The target calcium level should be about 420 – 460 ppm.  Best if dosed together with FEV Alkalinity Part B.

Storage: Store away from direct sunlight.
