The (4 Pack) of 1000 GPH Active Aqua Submersible Pumps were built to go below the waterline in your pond. Active Aqua's entire collection of pumps completes any grow setup, but for hydroponic systems, you can't beat the submersible line. All of Active Aqua's submersible pumps include multiple hose fittings so you get an exact fit every time. Each pump's powerful mag drive construction includes removable foam filters, impellers, rubber mounting feet to reduce vibration, and a 10-foot heavy-duty power cord. The Active Aqua Submersible Pump moves 1,000 gallons per hour and is recommended for 100 plus gallon reservoirs, but you can adjust the pump's flow to move at your preferred rate. And as an added bonus, with its dependable design, feel free to use this pump inside or outside. NOTE: Models 40 GPH-160 GPH contain a steel shaft and are not suitable for saltwater applications. Larger pumps (250 GPH-1000 GPH) have a ceramic shaft, and these are suitable for saltwater operation.
