Q on structure issues

[garvin90]

I want 2 210s or 240s in a corner(or side-by-side) plumbed together into one sump system.

I do need some advice on the big tanks. Could i have the sides drilled for a pass through pipe from one tank to the other or would this destroy the glass's integrity? The size hole im thinking would be larger, like a 2-3 in size or so. What im looking to do is have small fishes(or other critters) pass from one system to the next. The landscape theme would be a reef setup in one tank to more of a FOWLR in the other, with the 2nd tank acting as the rocks edge with lots of open space.

I was thinking of that too then after looking around I decided to build a plywood tank that is u shapped. You may want to look into a l shaped tank.

How do you build your own tanks?

The main reason for the 2 tanks was I wanted larger more open water swimmers like Butterflies that would pick on corals in the reef setup.

I would have thought that your idea doesn't present a problem with regards to the strength of the tanks. We frequently drill panels with several holes for overflows, closed loops, etc., without any adverse effects.
