Looking to build a system with a 75 display and would like to take advantage of the Petco $1 sale. Is a 40 gallon breeder tank sufficient for a sump? I'll be plumbing it in a room behind/below the display, so there are no restrictions. Would a larger one be better?? 55gal? Any advice would be appreciated..thx.
