I'm getting back into the hobby after raising children for 25 years. My last tank was a std. 55 with tinfoils and a pair of keyholes. I'm ordering a 72"X24"X25" soon and was wondering if anyone has ever had the returns from a sump plumbed up from the overflows but turned(90*) to exit low to drive the UGJ? That way they would be hidden by the BG covering the overflow boxes. If I ever wanted to change things I could just plug the bulkheads and go out the top. I have been reading on this site for a couple months now and have not heard of anyone doing this. Am I missing something? I have a hundred other ?'s I'll ask later. I've never posted before, so if I do something wrong..sorry.
