When culturing and maintaining coral communities in aquaria, maintaining an adequate alkalinity is critical. The majority of coraline species require calcium for developing the hard outer shells that protect them.
Calcium reactors recirculate small volumes of water across calcium media, injecting carbon dioxide in the water to reduce the pH. As the water becomes more acidic, the calcium media reacts to neutralize the water, releasing small amounts of calcium and bicarbonate. As the reaction occurs, the water is replaced at rates around 1ml/min to enrich the coral tanks. #corals#aquariums#waterquality#aquaria
