Calc Reactor

[Troy Valentine]

Thanks that's good to know. I'm worried enough about two-part so I'll hold off on the calc reactor.

You might want to look into a Kalk reactor since you are using a Tunze Osmolator. You can run it in-line from your ATO reservior. Calcium Hydroxide is awesome! When applied correctly it can solve a lot of problems with Ca, Alk, and even Phosphates.
