CO2 usage, Gone too fast?

[Dutch]

Well i ended up putting the reactor in-line just to try it. The reactor is actually one of those large whole house filters that I modified. With just bio balls in it for diffusion, it has drastically cut down on the amount of bubbles that I see in the tank. I will try pot scrubbers next and see if that helps. Overall though, I have been able to turn down the CO2 output and still maintain the levels in the tank that I need. best of both worlds? the NW really breaks up the CO2 and the agitation in the reactor churns it up until most of it is gone.

Sounds like a winning combination....I like the fact that you tried it instead of just wondering..

Some pics would be nice...

The filter canister has 1in inlet and outlets. I drilled out the middle and extended the outlet down to the bottom of the canister offset to hold the pump inside which is a maxijet 600. Drilled a hole in the top for the pump power cord and sealed with silicone. Removed the air bleed valve from the top and threaded in a fitting to attach an airline which feeds back into the sump pump inlet (any excess gas will be returned). Currently have the bio balls inside, but plan to replace those with pot scrubbers.

The maxijet inlet grabs a lot of the bubbles churning around in there and pumps them up to the top. The pump acts to agitate the water inside the canister to dissolve the CO2.
