Hang On Tank Calc Reactor


In Memoriam
Anyone know of any DIY plans/commercially available calcium reactors that would hang on the back of a tank? I have a 29g minireef that sucks up calcium like it's going out of style, and dosing every couple of days is getting to be a pain. I've looked around, but I can't find anything commercially available, although the possibility that I'm not looking hard enough is not out of the question, either :bum:
