From the beginning this tank was supposed to have pressure CO2, but with all the distractions of life I never got around to it, until now. Tonight I finished the reactor to go in the sump. I glued a 1" PVC cap to a 1" PVC coupling for the body of the reactor, then drilled and taped it for the brass air valves I'm using for the water inlet and the CO2 inlet. I cut two notches in the bottom to allow the water to run out the bottom. Sorry I didn't take any pics before I had it in the sump.
I built a stand to hold up the tank so I can work in the sump.
I T'd into the return line to the tank and ran it to one side of the reactor and the CO2 line goes to the other side, the reactor has a piece of filter foam in it for the water to trickle over in the CO2 bubble.
Well that's it for tonight, Next I will expand my CO2 manifold for another needle valve and hook up the CO2.
