Ok I would like to add a sump to my 55 gal DT. I have an extra 10 gallon sitting and I thought about getting another 10 gal and having it drilled for a fuge. So I would have a 10 gallon fuge flowing into a 10 gallon sump essentionally adding 15-20 gallons to my 55. The fuge is a no brainer to set up to me but any advice on how to place baffles and design of the sump would be great. I want to place my skimmer of course in the sump and heater. Thanks in advance.
