drilling the tank shouldn't be an issue if your sure the glass is not tempered, and your sure you can do it. put a rag on the inside to catch any glass dust. you'll have to trickle water over your cut and have a way to catch it.

Wingedfish,

thanks for the advice. I will try the powerhead method. The only place will be in my sump. do you foresee any issues running the venturi tube so long?

once again, thank you
