eheim problem

[brianyu]

hi guys ,
for a couple week , my canister filter (eheim 2213) keep shoot air . my question is how to get all the air out of the filter ?
i check the O ring, there is no leak .

I'd say check to see if the intake is sucking air at all or there is a crack in the intake pipe somewhere.

Make sure there are no air bubbles in the hoses anywhere.
