We had the tank built to fit in a certain place in our new house. Dimensions are 60" long,30" wide, 31" tall. It will have 2 overflows with 2- 1 1/2" drains in each overflow. We also had them drill four returns into the back and I plan on running two mag12 pumps w/ SCWD for the returns. I am gonna have to do a serious skimmer upgrade too as soon as I get the new sump built for this one. I plan on about 100gal sump w/ refugium.(maybe try out that Zenia in the sump Dakar has been talking about?) Anybody got a good recommendation for a skimmer to handle that much water? Also gonna have to get on the ball w/ that DIY light upgrade......Man I didn't realize how much work I just caused for myself until just now!
