How much Weight can my “Tempered Glass Desk” hold?

I’m planning to get a fish tank around 80-100lb (pounds), and I was wondering how much weight CAN my desk hold? will 100 pounds be a safety issue?

Answer #1
doesn’t look like it was made for anything heavier than 30 lbs. or so for each of the 2 major pieces
you’re asking for trouble with 3 times that much weight on top of just one of them
anyway, better ask the manufacturer

Answer #2
You need solid wood for that.
