TomCruise Posted October 11, 2015 Report Share Posted October 11, 2015 I have an eheim 2211 (classic). I'm trying to figure out the best way to get CO2 dissolved in my water. I hate seeing little bubbles coming out of my outflow and have been experimenting with reactors, but my flow rate doesn't seem to be strong enough to turn the little impellers that supposedly mix the CO2 into the water. I have a pressurized CO2 tank with regulators etc. I noticed I use a pretty popular canister filter, so I thought maybe someone would have found a solution, or have a suggestion for me? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
