Drilling and adding sump to JBJ cube

[Adam10045]

Can this be done? I want to add a small sump to this tank under the stand and will need to drill a hole to run lines. Is the JBJ 28gal cube tempered? Has anyone done this?

There are a couple videos on YouTube drilling Nano-Cubes. From what I've read, the sides and back wall are not tempered, but the bottom is. I always considered doing this to my Nano, especially since I've drilled almost every other kind of tank, just never got around to it.

That's the only thing I'm worried about. I want to make sure it's not tempered. I called the mfg and they wouldn't give me a clear answer to if it tempered or not. The filtration on these cubes just isn't enough for me. I'll do some searching on YouTube! Thanks!
