DrTim's Aquatics Waste-Away Natural Aquarium Cleaner for Reef and Nano Aquariums, 4-Ounce
Waste-AWAY Natural Aquarium Cleaner helps keep your aquarium clean and water crystal clear using novel sludge busting beneficial bacteria that will naturally dissolve the sludge and dirt that accumulates in an aquarium and prevent the build-up of waste when used on a regular (weekly) basis. Waste-AWAY is fast acting and specially formulated to remove aquarium gunk, unclog gravel/coral beds, and keep filter pads freely flowing longer.  Waste-Away reaches places in your reef tank you can't.  This results in better water flow, more oxygen and a healthier aquarium environment.  Waste-AWAY removes dissolved and particulate organics, reduces nitrate and phosphate and is 100-percent natural.  Contains no phosphate.  For reef and nano aquariums. 4-ounce treats 120 gallons.
