Taking Calcium reactor offline should I keep it going with c02 for bacteria


New member
I meant without c02 in the title ..I've been really battling with my tank lately and I've flooded the chemistry forum with threads sorry about that.. I really love this hobby and have since I was young. So sorry …I use both dosing pumps and cr lately been having issues with alk swings ,fluctuations ect . I am going to take out my cr for a little while and just dose via dosing pumps maybe?.... my question is should I completely remove the reactor or leave it be just turn off co2 for bacteria colonization? I dose vinegar is the only reason I'm asking .... Seems like it could make a good place for that type of bacteria if I wide open the flow? Or does that seem lame lol

I'd either remove it and drain the water from it, or keep the water flowing without CO2 to keep it from becoming anaerobic.

If you want to aim it as a place for bacteria to grow, I'd pick a higher surface area media for them to bind to. GAC, maybe, or some of the ceramic stuff sold for bacterial growth.
