Precision Marine has two ways Calcium can be added to your reef tank, the Calcium Reactor or the Kalkreactor pictured here. 

You can either gravity feed through the Kalkreactor from a freshwater top-off system to your reservoir, or use a dosing pump.

We chose a reliable water pump in lieu of the magnetic stir bar, which tends to jam, bind and wear the acrylic.

Our model also includes a threaded opening at the top to enable adding Kalk powder without removing the lid.

Master fabricated and computer cut, the KR620 is a very nice piece of equipment.
