well i now have my refugium and wanted to know what anyone thinks of my proposed setup. I have a bottom drilled 58g and i was going to do a pipe as an overflow raise the tank and have it dump into my skimmer section of my 50g oceanic sump you can see the holes in the oceanic sump. I figured i would use the smaller section for the skimmer and the larger for the return. heres a sketch the red is return the blue is drain and the green is the skimmer. Note its not to scale.
