Dr. Tim's Aquatics Waste-Away Natural Aquarium Cleaner for Freshwater Aquarium
Sludge and organic busting beneficial bacteria will naturally dissolve the sludge and dirt that accumulates in an aquarium and prevent the build-up of debris when used on a regular basis. Also removes dissolved organics. Waste-Away is fast acting and specially formulated to remove aquarium gunk, unclog gravel/coral beds, and keep filter pads freely flowing longer. This results in better water flow, more oxygen and a healthier aquarium environment.
