Anyone running a cerges? Do you get gas pockets forming at top of canister housing?
Mine does and the water drop noise is loud and annoying. It seems to be about 6in water drop. Mine is a 20in housing.
Any solution to get rid of noise? Other than that my reactor is working fine.

Mine also makes gurgling noises. It's been running for about a week now, and it does it every day. My drop checker turns yellow at about 4-5bps on a 60P. I attempted to add a small air stone to the end of the tubing to form smaller bubbles in the hopes they would dissolve faster. It may have helped slightly, with a few micro bubbles making it out of the reactor. I think the trick is to match the bps CO2 to the amount able to be dissolved. Try playing with your co2 rate and see what happens.

well if i play with bps rate, then I wouldn't get the optimal co2 level. I didn't realize this co2 reactor had a limit on what it can dissolve. It works fine if the bps were less, but mine is a 210g so the bubble rate is high.

That was the reason I got rid of my Cerges reactor. It just couldnt dissolve the CO2 I needed for my 50g tank.

Even Rex Grigg reactors suffer from this with a build up in gas by the end of the day. I've used both and thought the Cerges reactor was worse.

I'm much happier with an atomic diffuser tucked away in the corner of the tank even though everyone says they're less efficient.

those just don't work for a 210gallon.......large bubbles will be coming out of that diffuser lol.

There is no one 'standard' Cerges design so its tough to say what your problem could be. At best these seem to work well as a glorified bubble trap.

If you just have air accumulating in the top of the canister - drill a small hole in the top - insert an airline tubing and connect to a venturi on the incoming water line. This will pull the extra CO2 out and reinject it in the water allowing it to dissolve. Excess air bubble from the venturi will get trapped in the Cerges. You should see very fast consumption of CO2 and if the water flow is not too high then a bubble free tank.

Unfortunately the basic design on the Cerges described in TPT forums is lousy at dissolving CO2 since the design does not describe a way to increase surface area.

have you tried adding few pot scrubbers inside the reactor? this will increase the dissolve rate of co2 and make the co2 dissolve better.
