Why do you need a dosing pump?

Dosing pumps are required to maintain adequate levels of magnesium and calcium, and also keep the salinity and alkalinity of the water in check. Aquariums that have corals in them are very sensitive to the amount of nutrients present in water. Reef-building animals require minerals like magnesium and calcium to build the reefs. The plant life also needs essential nutrients and these pumps do this replenishment job for you without any hassles.
