At Precision Marine there are 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.

A reliable water pump is used in lieu of the magnetic stir bar, which tends to jam, bind and wear the acrylic.

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

REVIEW
I am giving this 4 stars, I would like to give 5, but it was leaking between the busing and gate valve.

I email PM support and was more than helpful. MD also was supportive. It was an easy fix with teflon, but it should be ready to go from start.

Would I buy another? absolutely.

REVIEW
I installed this on my Reefer 350, inline with a Tunze Osmolator to replenish evaporated water, replacing the gravity feed ATO that came with the tank. The osmolator feeds water from an RO/DI reservoir into the Kalkreactor when activated and this forces the kalkwasser solution into the sump until th...Read More

REVIEW
I spent a lot of time researching and this one was the best for my situation. Im supplying KW via a doser and the doser has a supply line in my top off container. This way I am not dependent on evaporation and can dial in how much I want to add. The unit isn't gravity fed so I don't have to worry...Read More

This is my second Kalkreactor and by all means the best. I am using my Apex system as a timer for this reactor that turns on once a today and stirs the solution. My pH reading as a result of this reactor is at a steady 8.35. I truly believe that my corals are benefiting from the addition of addin...Read More

REVIEW
I have run this reactor for about 3 years now on two different SPS tanks. The construction is high quality and the design is generally very good. A word of caution regarding the mixing pump, as others have said the impellers will break at least once a year if not more, so buy a few extra. I run...Read More

REVIEW
This product works great. My only downfall as to why I rated it a little low was because the top screw will leak - even with the O ring provided. I has to threat it with plumbers tape and caulking on the top to prevent it from leaking. Ensure you have the pump stirrer on a timer as it cannot run con...Read More
