Calcium supply for marine aquaria

The natural calcium concentration in seawater is approximately 420 mg/l. In the aquarium, the range should remain within 380 - 440 mg/l as far as possible. Below 360 mg/l, significant restrictions in the skeletal development of hard corals are to be expected.

Values that are too high lead to problems with the pumps and other devices due to precipitates, but bring no advantages that would justify this.
