Aquarium Advice Regular
ok i wanna get the glass drilled on my tank. it is a 125 gallon long tank (72,18,22). i hear that you can not get tempered glass drilled, so how do i find out if my tank is tempered. also will a glass shop drill it for me? how big of a hole do i want and how far do i want the hole from the top of my tank?
