The natural look that sand provides makes this one of our favorite substrates to use in an aquascape. Sand found outdoors or at the beach can contain contaminants which may be harmful to your aquarium. Regular playground sand clouds water during initial use or if stirred up by fish because its so fine.
Buceplant's Fine Natural Sand is specifically made to be pet safe and suitable for aquariums, terrariums and more. This is the sand we've used in all of our scapes!
