Cheryl's 165 Gallon upgrade

[CherylMcKay]

How far should the water fall? My internal measurements for depth of the tank, is 21". I was thinking the over flow would be 12" deep with 1-11/2 " for the egg crate. The fall to the bulk head will be 10 1/2 to 11 ".

I am thinking my overall dimensions will be 48"x 7" x 12"? I was thinking 7" as my Euro-bracing is about 3" wide, and this will allow me to get my hand in.

Thoughts?
