This is the fish tank with a surface aquafarm that creates a symbiotic relationship that helps plant live and fish thrive. A plant tray on top of the aquarium keeps plant roots submerged and the included beneficial bacteria convert ammonia-rich fish waste into nitrates and nutrients that help plants thrive. The tank has a built-in pump that constantly delivers waste to the plant tray and the plants convert the waste into food and clean the water in the process. The 3-gallon acrylic tank holds up to several small fish and supports five plants. Includes organic wheatgrass and basil seeds, bacteria, gravel, hydroponic growstones, and fish food. 9 1/2" H x 13 1/2" W x 13 1/2" D. (8 lbs.)
