Use 1 to 2 pounds of substrate for every gallon of aquarium water. Rinse thoroughly in cold, clear water before using. Never use soap or detergent. To prevent disturbing the gravel when filling your tank, pour the water onto a saucer placed on the substrate. Fill aquarium halfway, then remove saucer and add dÃ©cor and plants before you finish filling your aquarium. Once your aquarium is established, do not wash the substrate. Use a gravel vacuum once a month, or as needed, to remove loose debris.
