In my 120 (4') high tech tank I've been having some trouble with surface scum. I don't really feed the tank (only have a few fish that live off what they find), so it's not from that. I originally had a lot of organics in the tank (dead plants, etc.), but even several days after vacuuming out all of these the surface scum remains.
I have an Eheim 2217 spray bar and a Hydor Koralia Nano 240 pump at the surface moving water around. The scum is present everywhere besides the immediate the reach of these two. Any tips to get rid of it?
