not sure on how to notch glass.
but i had the same questions in regards to overflow teeth requirment and how high the water would rise going through them.
I believe RC has a calculator for determining flow through overflow teeth.
What i discovered was ... it really depends on your return pump and overflow design. try and find that calculator and see what it says .
I believe thats why some people have a valve to restrict there return pump. to help them adjust water height. .
For me , when i fired my tank up with the mag 9.5 , i found that my teeth and overflow combo was to restrictive and forced the water level way up the teeth.. I broke a few teeth out and the level dropped
