The Hagen Elite Aqua Fizzzz Air Stone 4-Pack is ideal for adding accents in any aquarium. The air stone diffuses air creating water movement and saturated oxygen (O2) and burning off toxic gases that can kill animals. The Elite Aqua Fizzzz Air Stone also increases surface agitation, accelerates oxygen replenishment and helps release carbon dioxide build-up. Simply connect the air stone to your airline tubing and place it in desired location.
