Film and Flow

[FUIceman]

Hey all,

I'm having a problem with surface film build up. I could use some help understanding possible fixes. Here is my problem as well as my power head setup.

You can see that the most film buildup appears to be in the return area. That film does not seem to move, but rather sits right at the return. I'm about to do a 20% change, but thought I'd ask. Is that normal, or do I have a flow issue?

Thank you for your help.

If u have an overflow you shouldn’t be getting film. I have film on my tank w/out any overflow and just a powerhead

Thanks for the response. I do have an overflow, which confuses me why I'm having this problem. It's a fusion 10g with built in sump. Doesn't make sense to me other than my flow must be incorrect. Looking for suggestions to make it work better.

I have the same exact issue. Did you figure it out?

I had the same issue and I raised my return pipe to just above the water line. Broke it all up and have not had the film return.
