Think I have my last 2 big oscars sold Friday so I can finally start thinking bout setting this thing up with saltwater. Iv read on a few forums were people have cut the old ones out blocked off the bulk heads on the bottom of the tank and redrilled the back and installed different overflows. Overflows are something I'm not real familiar with as I just drill the tank install bulkheads and plumb them no protection ect over the bulkheads can't count how many fish are in my sump now due to my horrible design. What's a good alternative? Plan is setting it up as a wall divider. With that in mind Iv been thinking of drilling one of the sides on the tank and have the plumbing hidden. Anybody have any pics of what they have done? Any opinions will be greatly appreciated
