Spray foam for 3D background

[jpierce3]

I was wondering what product was best used for 3D backgrounds? I saw the Great Stuff at Home Depot, but didn't know if it was fish safe and if there is a cure time recommended before putting it a tank with fish? There were several different types so I want to check before I buy some.

Thanks if anyone can help out.

Great Stuff makes a product specifically for ponds. You want that. I think the other stuff is probably fine as well, just make sure there is no anti-bacterial chemicals added.
