Drilling 3 holes in a tank would make me nervous... not the drilling part, I'd be worried about the tank cracking over the long term. Would it work or be helpful to silicone an extra piece of glass with holes drilled in the same locations to help reinforce it? Or is that a stupid idea?
I know I'd be very interested to find out as well since I plan on drilling my future 40br.You'd think that they would have some diagrams or calculations somewhere with that kind of information G/l and remember it's a learning experience!
