Microbubbles!!!!

[reborn258]

I have a cascade 1200 canister filter and every time I increase the flow I get tons of microbubbles. When I reduce the flow the bubbles still come out but not as much as the stronger flow. I tightened the hose near the valves and checked everwhere else it seems fine to me. But I can't get rid of the bubbles. What can it be or what can I do?:help:

Did you just set up this filter or have it open recently? It might just be air trapped in the canister purging out. You could also possibly have a small airleak somewhere. Try putting some silicone gel on the o-rings. (I think the silicone would be SW safe, not sure you'd want to use vaseline.)
