The KORALLIN calcium reactors are one of the top performers on the market allow  you a simple, elegant way and with high efficacy to produce calcium hydrogen carbonate including the necessary balance carbonic acid and the fish-tank water continuous lead. It becomes ready for immediate use operating with integrated Eheim pumps (ceramic axis + carbon bearings) with special substrate supplied to the connection to usual CO2 devices, and are used for the highest quality control requirements. On account of its small overall it can become readily set up under the fish-tank, also into the filter box!
       
In the coral reef tank, the calcium hydrogen carbonate content is an important parameter on which the lime formation and therefore the growth of the corals at decisive measure depends. He takes strong influence as a main component of the bumper system to the pH-value. Without suitable countermeasure accompany very soon it to lime lack combined with growth reduced at least strongly lime consuming organisms.
