Well, Ive decided not to use the sump/fuge that came with the tank I bought used. I am planing on using my 55 gallon for a sump/fuge using glass baffles. Does anyone have any plans for a 55 sump/fuge they have used before or can maybe help me design one? I have read Marc's site, but would still like a little direction, or plans for something that is known to work. Any help is appreciated. Thanks!
