I looked into the racks, and some can hold 1500 lbs, 2250 lbs, 2500 lb per shelf. I don't see why they wouldn't work or why they shouldn't be trusted. But please look at a few of the links below and tell me your thoughts, maybe you'll see something I overlooked.

We used that black husky in our fish room for awhile. Lots of 15 and 10 gallon tanks.

It is very strong and well made, that's the good news. The wire shelving is crap though. We didn't trust it. We put 3/4" plywood cut to sort of fit. (You can't make it fit exactly unless you are installing the plywood as you assemble it.)

You can really only get 2 rows of tanks on it though. Doing the bottom row would be a maintenance nightmare.

It's also pretty industrial looking, this is certainly for a fish room, not a living room.
