Rinse thoroughly in cold water before using. Never use soap or detergent. When filling your tank, place a saucer on the gravel and pour water onto the saucer. This will prevent the water from disturbing your layer of gravel. The aquarium gravel will become a home for beneficial bacteria to keep your aquarium healthy.

Monitor your water pH after adding gravel and adjust as necessary to avoid sudden pH changes.
