I have a Deep Blue 34g RR rimless frag tank and I’d like to drill a return on the back glass opposite corner of the drain. I came across this..
It says non-tempered, but the bottom is.
How can this be. The bottom corner is drilled with a 1” drain and 3/4” return. I’d like to use the 3/4” as a main drain and the 1” as a back up.
