Keep your finned friends happy and healthy with the powerful cleaning action of the Aqueon QuietFlow LED PRO Aquarium Power Filter. This filter is designed with a strong but quiet submersible pump that is conveniently self-priming on setup or after tank cleanings. It exposes the tank water to oxygen for cleaner water and more active fish all while removing debris and toxic ammonia. With five stages of filtration, including mechanical, chemical and biological, your fishy family members will benefit from clean and clear water. Best of all, it features an LED light that lets you know when it’s time to replace the cartridge!
