We purchased a used 210 gal set-up with a 75 gal sump. From what I have read on this forum, I do not think the sump is set up in the best manner but I don't know enough about them to decide how to change it.The overflow runs through a trickle filter down to the rock and the skimmer is sitting in the same area that the LR is in. There is only two sections in the tank. In the picture you can see on the right that I'm having some slimy foam in the return pump area. I'm thinking that the LR should be after the skimmer and that I should put in an additional section or two? There is plenty of room.
