Get ready for some serious science, because with the Back to the Roots 3 Gallon Self-Cleaning Water Garden Fish Tank, you and your kids are going to get a crash course in fish, fun, and sustainable aquaponics ecosystems! This 3-gallon fish tank doubles as a garden. Not only is it a self-cleaning aquarium, it also allows you to grow sprouts and herbs right at home. This water garden is perfect for hands-on family or classroom projects with kids. Watch as they discover how the fish feed the plants and the plants clean the water. This kit comes with everything you need - the bowl with custom grow pods and grow bed, gravel, organic seeds, grow stones, fish food, a silent submersible water pump, and a coupon for your very own Beta fish. Just watch: Today your kids could be learning about ecosystems with this fish tank garden. Tomorrow they could be walking across that stage with their Ph.D. in ecology.
