It can be worthwhile giving the fluval filters a sturdy shake from side-to-side every once in while as they can get trapped with air somehow. As good as they are they do have some basic flaws that can break them rather too easily. Once a month with mine i tilt it about 45 degrees each direction and give it a wobble to remove trapped air, usually does the trick. Then every 6 months i give it a thorough taking apart to clean it out properly.

I have to give mine the wobble treatment every time I do a water change, the primer seems to be a bit useless (or I can't pump hard enough, no jokes please!). I have to admit to not being very impressed with it.

Yeah, air bubbles get sucked into the filter and cause airlocks. That's what's causing the "big blows".

I only know this because I had the same issue, (Oddly with my 405), so I just moved the airstone so it's not near the inlet. Is fine now
