I mentioned later on that I forgot my system is reversed from the typical system. I don't have an overflow in my main tank thus you can see the surface scum from my pic. I didn't make that up. Basically, I'm saying that I made a mistake in my first post because my main tank IS like a typical SUMP and my sump is like the typical main tank.
