I'm having lots of problems with my Aqua Medic CO2 Reactor. Biggest problem is that it has a small pump that circulates H2O into the diffuser to mix with the CO2. The pump not only pumps H2O to the diffuser but also pumps H2O out the small hole where the CO2 tube connects, and therefore puts back pressure on the CO2 tube and closes the check valve. If I turn the CO2 (needle valve) up high enough, it overcomes the check valve and I get CO2 into the tank. If I turn the CO2 (needle valve) down to the proper bubble rate, then it can't overcome the back pressure on the check valve.
Anyone have one of these diffusers (that works properly)? Any recommendations for a better diffuser?
