View Full Version : Air bubbles Magnum 350

I put in a Magnum 350 to run Carbon in my tank it seems to be putting out a lot of bubbles. I thought it would eventually just spit out all the air then all would be good. In the morning I checked the canister and there is actually more air in it now and still lots of bubbles any thoughts. Maybe there is a small leak where air is getting sucked in. Has anyone had this problem before.

you need some silicone grease. Put that on the O-Rings for the inlet and outlet and also the orange "D" ring for the lid. This will solve your problem.

Of course this is assuming you left no air pockets in the canister when you first filled it. I have noticed it can take a little bit of time for the air to be drawn out completely if I left some.
