What I mean is a ReefREady tank with the overflows on the OUTSIDE of the tank. How would this work?? Inter-american is putting them on and saying they are great. Do you guys forsee problems. It would sure free up ALOT of space INSIDE the tank!!! If I have a 2 inch drain on the bottom of these, they are drilling a 3 inch hole that will be like a "notch" LET me know before I order.
