Great Stuff spray foam in shark tank?

[Reefmike]

Has anybody used the spray on foam in their shark tank?
I'm thinking of building some cave/rock support structures out of acrylic as well as pieces of eggcrate with some small shelves covering the back then spraying the dark colored foam over the back and structures. As soon as it's sprayed I'm going to sprinkle sand on it and stick a bunch of rubble everywhere and probably some bigger pieces of base rock over/around the caves.
TIA,

There is a spray foam called "Great Stuff" which is aquarium safe..

****Edit...LMAO...i just noticed you put "Great Stff" in the thread title, so i presume you know of that brand of spray foam....

just make sure it fits back in the tank and you'll be fine.

but id let it air out for atleast a day, just to be safe.

just dont leave it in the sun (UV light) it causes some type of damage to the foam

Yeah, its fine to use in a shark tank. In fact, I just got done DIYing my structure for my shark tank.
