The Fluval Betta Premium Aquarium Kit is the perfect way to create your own custom aquarium environment. With up to six stages of filtration, this kit includes everything you need to get started. The diffusion chamber disperses flow and polishes water during the final stage of filtration to mimic clean, slow-moving currents of indigenous Betta habitats. The LED lights are energy efficient and create a relaxing atmosphere that will make your fish feel right at home. The fully integrated pre-set 10W heater consistently keeps the tank at an ideal tropical temperature of 78 degrees Fahrenheit or 26 Celsius.
