Aquasonic Calcium-Sup provides calcium for corals and marine invertebrates
Essential for all marine life. Aquasonic Calcium-Sup is used to raise the calcium level of a reef system, quickly and safely. One treatment raises the level by approx. 50ppm. Natural seawater contains calcium levels of 380ppm but this level however may be depleted in closed circuit aquaria. Calcium levels of around 400 to 450ppm encourage the growth of hard corals and coralline algae. Molluscs, crustaceans and some marine plants will also benefit.
