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

Directions for use: Add 5mL per 20L of system volume to raise calcium by approximately 50ppm. Before re-treatment test levels with an Aquasonic CALCIUM Test Kit. Treatment may be applied in smaller doses over several weeks if required. It is recommended that a water change of 25% or more per month be made.

Usage guide: To calculate approximate aquarium capacity: length x width x water level height (in cm) and divide by 1000 for litres.
