Are you guys doing anything special for diffusing the CO2 going into the Tee fitting? Also, i ran my setup so the output of the canister went into the output of the reactor. This means the water coming in goes down the tube in the middle of the reactor. Problem I'm having is the bubbles I'm getting are large and don't break up in the tube. They just go right thru the tube and out into the reactor as large bubbles right into the tank.
I'm think I have it backwards and need to have the water going into the reactor go into the large canister portion and the middle tube is then getting water from the bottom if the reactor and pushing it to the tank.
Here's my setup. Tried adding a gauge at the top of the canister since I was reading a lot about internal pressure helping disperse CO2. Running with ball valve wide open on the marineland C220 it shows no pressure. If I cut the output back some I can get a flicker and if I cut back nearly all the flow I get maybe 1-2psi.
The valve on top is so I can bleed the air from inside the canister.
