In seawater, a stable calcium value is essential for the healthy development of corals and coralline algae. Aquaforest recommends 380-460 mg\/L (ppm) in reef tanks.\u003c\/p\u003e\n\u003ch3\u003ePrecise manufacturer dosing\u003c\/h3\u003e\n\u003cp\u003eDissolve 50 g of Calcium in 1000 ml of RODI water. 100 ml of this solution raises calcium by 18 mg\/L (ppm) in 100 L of water. For one-time adjustments, 10 g in 100 L raises the level by about 36 mg\/L. Never raise calcium by more than 20 ppm per day, and test your water before every dose. Calcium and Magnesium can be combined into one solution.
