Well, it's now 1:00 in the morning, and after sitting around looking at my tank, i just realized, sense im getting the new acrylic 20 gallon display tank tomorrow, im going to have this basic 20 gallon glass tank sitting around(the old display tank), then i thought some more (knew i should of fell asleep sooner!) Well, would there be a way to have the 20 gallon off to the side(on the floor) and a way to plumb it in with the refugium, giving me more area for the fuge chamber and being able to set the protein skimmer inside of the other 20 gallon "sump" with LR rubble? Basically, heres a picture of what i would like to make work...if possible... The 20 gallon basic and 10 gallon fuge are NOT drilled and don't plan on it, so would there be a way of making all this work?
