The calcium provides the necessary elements and molecules for the growth of reef-building organisms such as corals and their allies. Corals and other reef-building organisms require sufficient and stable available calcium and alkalinity if they are to flourish, but you have to calculate for daily dosage, and it’s kind of annoying. ​
​

Let the T-Series Do Calculate for You​
JNS cTech T-Series Calcium Reactors use an up-flow design to mix saltwater, calcium carbonate and CO2 inside a reaction chamber to eliminate the need for daily two-part dosing. Not only will the JNS cTech T-Series Calcium Reactor keep your levels balanced, you will no longer have to calculate daily dosages for your tank. With a seamless body, removable lid for quick media access and a small, space-saving design, the JNS cTech T-Series Calcium Reactor is truly one-of-a-kind.
