Choose a pump that was built to go below the waterline! Active Aqua's entire collection of pumps complete any grow setup. You can't beat the submersible line, as it is built for hydroponic systems. 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 6-foot heavy duty power cord. Adjust the pump's flow to get things moving at your preferred rate.Specifications250 gallons per hour Recommended for 25 gallon reservoirs16 Watts/120 VACFeaturesPowerful mag drive constructionIndoor and outdoor useOil free and environmentally safeBPA free—safe for aquaponic useOne year warranty6' power cordUL-listedNOTE: Models 40 GPH-160 GPH contain a steel shaft and are not suitable for saltwater applications.
