BTW, I think part of what I do not like is that my tank isn't RR. There didn't happen to be any RR 125 -150g when I got my tank, so I had it drilled in the back and went from there. The RR's just look so much nicer, are so much quieter, and seem to have much better flow (maybe it's just me). Think I might keep my eye out for a RR tank, get a bigger sump for more room and filtration, and then think of reasons why I need another tank, possibly bigger, to my wife whom isn't involved in the hobby at all besides just looking at the fish and corals (once I get some).
