What are the thoughts on infusing CO2 through a small powerhead, with a venturi fitting on the powerhead? I am trying to get the bubbles smaller, and pushed through the tank more evenly. My plan is to connect the CO2 feed line to the venturi inlet on the powerhead. The impeller should break the larger bubble into lots of small bubbles, and be pushed into the tank by the powerhead. What do you think? My only negative though is, will the powerhead by pulling co2 from the reactor collapse the bubble counter bottle from too much suction? I have just built the reactor, and bubble counter, and am waiting for the silicone to cure. If this don't work, I am going to use a modified Hagen Elite Mini in tank filter.
