Hi,i was wondering where you can get the diy overflows i see people make?i also would like to know what i would need to drill holes in aga tanks for bulkheads and overflows.Any pics or help would be much appreciated.Thanks Kevin
Kevin,
do a search for "diamond bit" here, You'll find out info on glass drilling. If you're not into making the overflow, check your LFS. They will have them or be able to get them for you.
