We are moving the 6' 125g into a 6' 180g and we would like some input as to where the holes should go for overflow to a 30 gal sump. We are tired of depending on an aqua lifter to drive the overflow. Holes at the bottom for the factory overflows is out of the question with no discussion and from what Ive read overflows with holes at the top make alot of noise which is not a problem. I have no other options, I cant get glass cut(bean type) its either hole(s) at the top or use the aqua lifter type overflow. thanks.
