I have a sump for my 120 gal reef tank. Its an Eshopps with a dual return on one end. The skimmer takes up a lot of space in the middle chamber where the refugium would be. Do we need a skimmer if we have a refugium? Also, I tried to do the refugium when I first started, but the cheato kept rolling over the space between the middle chamber and the last chamber where the pump is. It seemed like there was just a lot of flow through the sump. I thought the pump for a 120 gal system had to be pretty strong to turn the water over enough. Any suggestions for a system overhall?
