Re: Airlock in Eheim Canister filter

If your filter is just set up it may not be 100% filled with water ? I have
this in my canister filter usually after a couple of hours it stops. Where
is the CO2 diffuser connected to ?
Do you might have an air stone that bubbles into the intake of the filter ?
Did you try shutting it off for a couple of hours ?
