Aquarium & Terrarium Gravel & Substrate Glofish

GloFish Aquarium Sand sets the stage for a unique aquatic experience. This white sand with fluorescent highlights not only provides a base for all your GloFish ornaments and plants, but it also looks magical under your GloFish aquarium's blue LED lights. Use 1.5-2 pounds of sand per gallon of water. Rinse sand before using. To clean your sand bed with a gravel vacuum, care must be taken to avoid removing the sand by limiting the flow rate through the siphon tube.
