I think this is the way I will go. I look forward to seeing it re-build.

+1 on the bean animal overflow. It also has the benefit of being external, and getting rid of overflow boxes in the tank is a huge asset.

If for whatever reason you do decide to go with a herbie, my only word of advice would be to consider how many over flows you need, and how they're all plumbed together. A tank as large as yours is a candidate for have two overflows, and if you do that and also want a herbie, don't plumb your overflows together. Have the overflow lines run completely separately in to the sump (as in, two pipes spitting out water in the sump). If the overflow pipes are joined at some point beneath the tank before they empty in to the sump, the herbie's will be infinitely more finicky, and horrendous to deal with.

I had to abandon my herbie overflows and go to a durso because I had my overflow pipes plumbed together under the tank.

My next tank will have a Bean Animal and external overflows.
