I'm wondering if the bottom of 93 cube made by marineland be drilled? I've read some answers posted on marineland's website and they said all panels are not tempered (see picture). Did anyone attempt to drill another hole before and successfully?
It's currently has two 1" holes drilled...one for drain and one for return so I would like to drill another 1" for the drain. Thanks for the help.
