Just picked this up at the Container Store near me, want to make sure there's nothing wrong with it where it wouldn't work as a quarantine tub if set up with proper filtration/heat.

Basically, I need to know that this won't be some kind of plastic that will randomly poison my fish. Normally I'd quarantine in a little 10g tank I've got, but this is a 13'' fish so that's a no-go. My plan was to put my backup canister in there (with a small internal filter or possibly sponge filter) and a heater. Should I be concerned about the heater melting the plastic? If so, should I put a small layer of substrate on the bottom to stop that from happening and just lay the heater on that?
Any thoughts are appreciated. And no, I'm not putting the cat in there.
