thanks guys - now for the big question on drilling - i take it being tempered glass i cannot get the bottom drilled so a back glass external durso is what i had in mind. Figured one on each end but how far down from the top lip and how big should they be drilled? Which size pipe seems to work the best for flow? I really do appreciate this - i will be doing this right the first time so any proven methods are welcome. I search the threads and see some good idea's but not alot specific to a 150g.
Thanks again guys and gals
