SAND - Views On Playsand For The Aquarium?

Play sand, provided it is not white play sand, is highly recommended for aquariums. It is fine, smooth and cannot contain anything nasty that would poison children if they eat a mouthful of it. It is cheaper than "aquarium sand" and is equally as good for fish tanks. But like "aquarium sand" it will contain dust which will need to be washed out before use.

White sand, whether play sand or intended for any other use, is not recommended for aquariums. The glare from the tank lights reflecting off white sand is not appreciated by fish. And it shows every speck of mess.
