Thinking of getting rid of the Sump

[Borderjumper]

I don't have a sump in my RSM and I don't think you need one. I use a little bubble Magnus skimmer in the back chamber.. It fits ok but I have to leave the little lid thing open. It's going to get a little warm in the summer, but leaving the little back lid thing open and setting a piece of egg rate over one side with a comp fan running solves the heat problem.
