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?
 
Is this a new or used filter?

What media is in it and how do you have it placed?
 
If the problem comes back after you burp your filter there may be a way the air is getting into your canister. Do the marinland canisters come with disconnecting valves? I would double check the hosing. Finer media also tend to cause micro bubbles when clogged.
 
If you followed the instructions for assembling the canister, have all the trays in the proper position, primed the filter properly and all the connections are tight, you shouldn't be seeing this problem.

Is there any chance your intake strainer is sucking in air from the power filters or the powerhead? Do you also have an air bubbler, stone or wand in the tank?
 
OK so over the weekend I took it all apart again and greased all rings and re-tightned all fittings. Turned it on and burped it. This morning it is still blowing bubbles. I have emailed Marineland to which I got no reply. I am considering boxing it back up and returning it to the LFS I got it from. Would a Fluval FX5 and a Fluval 405 be plenty of filtration for an overstocked HAP/Peacock 125 gallon?
