Looking for Ideas to build a stand for a 75gal DT with a 40B sump, so far this is the only one I've seen....don't mind the plumbing 'cause my tank in pre-drilled at the bottom, been that both tanks have the same deep dimension (18 1/2") I'll have to add couple inches extras to the bottom part of the stand to be able to feet the 40B sump....any other way I can do this?
