The BlueStone 900 gph water pump is a fully submersible, or inline, magnetic drive pump offered only by General Hydroponics. Used in our popular AeroFlo2 30 and 36 units. Blue Stone pump comes with a sponge pre filter and 1/2" fittings. Because it has only one moving part, our BlueStone pump does not require bothersome replacement seals.
