Now available - The new Aquarium Co-Op Power Head. No need to rearrange your entire system to find a plug for it, since the included extra long power cord measures 11.8 feet to reach any outlet. It can be used on its own or with the Aquarium Co-Op Sponge Filter to create a more powerful filtration system. The power head itself works by sending water up through the bottom intake and pumping it out the top horizontally across the aquarium. Ideal for any aquarium in need of increased circulation. Circulating over 200 gallons per hour, this power head is suitable for even larger aquariums to provide additional flow as needed.
