Drilling 29 gallon biocube

[Tobykourtney]

Is it safe to drill the back of a 29 gallon biocube? I noticed the glass is only 5 mm and online info is conflicting.

Im a bit late here but is the back tempered? You can call the tank makers to find out or use polarized glasses to see. Look at the back window of your vehicle. They are all polarized. They have invisible squares in them. If the back of the tank doesnt then your safe but I would call and verify

I already decided against the biocube the glass is to thin for me to chance it. Thanks for the help though
