i plan on having the glass company drill some holes for me so i can make overflows... i just need some help on how big, and the best placement for them..

tank is 8x4x18"

thanks,
~john
 
I would think that you are going to need at least 2 overflows. I would have them centered 2' from the sides and 3" from the back of the tank. I would go with holes that are around 2" in diameter, but make sure that you can get a bulkhead for that size.

Good luck with the tank and post pics when it is done!
