Steve, yes the overflow is an issue. While the tank was being built I started to buy tunze equipment for it, I have a wavebox, 3 6100's and a multi controler. The way it looks I may just keep 1 6100 and get a wavey sea to turn it, but like you mentioned I don't want the stream so far into the tank.
Matt, thanks but I think Steve can help me decide, he's got the same issues I have with the euro bracing.
Believe it or not I'm getting pretty good water movement from 3 hydro flows on 3 returns, 2 on the overflow end and 1 under the rock work at the other end of the tank.
