So I have had this canister for about 2 weeks and although it appears to be doing its job I am getting bursts of air bubbles every so often that it has filled my 125 with bubbles to an extent. I have checked all connections and all seem to be snug. I have tilted the canister back and forth trying to release the air and it seems to be ok for about an hour and then the bubbles come back. Any other ideas what could be causing them?
