Will this work?\n\nDisplay Tank - 75 gallons\nOverflow - 1500gph glassholes kit (1.5" dual)\n\nSump - 29 gallons\nLayout - Skimmer/Return/Refuge\nReturn - Eheim 1262 (900gph)\n\nGiven the length of the sump tank (30") I don't have a lot of room for a fuge, maybe 7-8 gallons worth. The return pump will feed the refugium and the dual .75" returns going into the DT. There will be a ball valve on each one.\n\nThe bubble trap baffles are 15" tall, and the refugium is 16". The tank itself is 18.75".\n\nWill the 900gph pump be too much flow through the sump, split three ways?\n\n-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\nI could stuff a 55 under there, but I'd have to pick it up off a craigslist, which wouldn't be cheap. (Everyone in alaska thinks they own something *special* and want too much.)\n\nI also have a 20g long not being used, I suppose I could turn that into a two chamber sump and then turn the 29 gallon into a large refuge by itself; maybe gravity drain it into the return of the 20g being that it's 6" taller. But that's getting a little complicated.\n\nThoughts? \n\nThanks!
