The Quiet One 4000 Pro Series is a powerful, energy-efficient, and versatile aquarium pump designed for both dry and submersible applications. Appropriately named, this multi-purpose pump operates in virtual silence while dishing out an impressive 991 gph. It features a patented ECO-SAV system that generates more pumping power while consuming less energy. For added flexibility, a flow control valve with pre-filter grill is standard equipment.
