Hi guys, I love this site. I was hoping my first post would be an intro to my 29g nano turned out, but instead I have a question. I just picked up a 29 gallon tank at the Petco dollar-a-gallon sale. My temper detecting drill reminded me with a crash that the tank I was going to use was a Walmart special. anyway, I want to drill the tank for an overflow. Should I drill the bottom or the back and why? (Either will work with the stand.)

Thanks in advance,
John
