In natural environments, such as in the deep blue sea, coral reefs have access to enough calcium that can help the corals develop their exoskeletons over a period of time. Corals absorb calcium during formation of their outer shell, which makes this chemical really important to their growth.
In artificial environments, such as an aquarium
, calcium doesn't come naturally. However, a device called calcium reactor can be used to supply the much-needed chemical to the aquarium. A good and reliable brand is the AquaC RX-1 Calcium Reactor from Pet Store
, which does exactly that - disperse calcium into the water tank. Note that the calcium itself (or media, as it is often referred to), is sold separately.
Aside from calcium dispersion, the AquaC RX-1 Calcium Reactor also maintains the balance of alkalinity in the water. It can also be used to recirculate CO2 and improve oxygention within the tank. The triple-purpose function of this device makes it an excellent and practical buy.
The the AquaC RX-1 Calcium Reactor is only 16 inches high, making it one of the most compact calcium reactors in the market. It takes up only a small space, yet it can be used for reef tanks with as much as a 400-gallons capacity.
