OK - so I was wondering, I know this will probably make me sound like a moron, but does play sand harden when it comes in contact with water? Is that the whole point to it?
I want something at the bottom of my tank to make it look nicer, but if I put sand in there, Gnarles and Little Foot will only kick it up and make the water foggy and whatnot, so that got me wandering what would happen with play sand. I've never heard of it until I came to this website.
