dreams Posted May 10, 2009 Report Share Posted May 10, 2009 Hey guys I have a pressurized CO2 system setup with a ceramic Glass diffuser. I've noticed that the diffuser requires a certain amount of pressure before it will let CO2 bubbles pass through it. When the CO2 is shut off each night, i find that by morning, water has gone into the diffuser and up the tubing to where the water line is, and thus each morning when the CO2 is activated again, it takes sometime for the CO2 gas to push the water back out the tubes and diffuser before it gets released into the tank again. The problem with this is that it takes a long time for this to happen, often hours. Does anyone else get this problem? Is it that there could be a leak somewhere? I have put the tubing underwater before with pressurized Co2 running through it, however i have not noticed any leaks. Or could it be that the Co2 is being absorbed into the water in the tubing, thus replacing the gas with Water? Any ideas/solutions would be appreciated guys Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted May 10, 2009 Report Share Posted May 10, 2009 the CO2 should be left on even at night. that should solve your problems, HTH. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted May 10, 2009 Report Share Posted May 10, 2009 You should have a non return valve on the system. Quote Link to comment Share on other sites More sharing options...
