Corals heavily rely on calcium in order to grow, develop, reproduce and survive. If you have a reef aquarium
, your tank needs constant supply of calcium. However, when other organisms grow in your aquarium (and they surely will because an aquarium is a complete ecosystem in itself), they use up calcium and remove alkalinity from the water. This leaves the corals with not enough calcium for their needs. An obvious solution is to add calcium supplements, but doing this constantly is impractical and expensive.
If you want a a long-term solution that will save you time and money in the long run, go for a calcium reactor, which is a device that regulates the calcium and alkalinity levels inside a reef tank. In particular, it retains the proper ratio of alkalinity to calcium.
A calcium reactor has a chamber that holds a substrate with a calcium base. At normal pH levels, the substrate doesn't dissolve, But at lower pH levels, it dissolves and frees up alkalinity ions and calcium to the water.
Given its mechanism, it's important to have a constant supply of the substrate. You can do well with having a supply of D-D Rowalith C+ Calcium Reactor Media from Pet Store
. This substrate media is ideally used with Deltec reactors. It has a great blend of Rowalith W and Rowalith C. When dissolved, it releases a very high calcium output, higher than other brands of media.
D-D Rowalith C+ Calcium Reactor Media is made from natural calcium sources so it never contaminates the water even when dissolved.
The recommended media for Deltec Fluidised Calcium reactors and is 50:50 blend of Rowalith C and Rowalith W.Instructions for use of ROWAlith C+
This material must be washed very very thoroughly before placing inside your Fluidized Reactor, if you do not do this the reactor will run cloudy.
ROWAlith-C is a natural material specially chosen to produce the highest calcium output in your Fluidized Reactor.
Set the reactor to run between 30 to 40 dKH. Measure the water from the reactor after allowing it to run for 24 hours, from the output flow.
Due to the efficiency of the fluidized reactor constant top up of this material will be required. Please ensure that the calcium levels in your aquarium do not exceed 480 to 500 mg/l.
