Choose a pump that was built to go below the waterline! Active Aqua's entire collection of pumps complete 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 6-foot heavy duty power cord. Adjust the pump's flow to get things moving at your preferred rate. All pumps have a 1 year warranty and are safe for indoor and outdoor use. These products are UL-listed, oil free, and environmentally safe.
