Waste-Away is a unique combination of bacteria that attack and dissolve organic wastes in the aquarium quickly. Even with good maintenance and monthly water changes, sludge and wastes remain in the aquarium in hard to reach and hard to see places. Waste-Away, a 100% natural, beneficial bacteria-based product, works quickly to find, break down and remove these wastes. Waste-Away also removes phosphate and nitrate. Waste-Away works to remove aquarium gunk, unclog gravel beds, and keep filter pads freely flowing longer. This results in better water flow, more oxygen and a healthier aquarium environment.
