A water treatment feed device includes a hopper and a receptacle. The hopper has a granule-receiving compartment defined by an upper hopper portion and a lower V-shaped hopper portion connected to the upper hopper portion. The lower V-shaped hopper portion is fabricated from a porous material having a plurality of pores sized to at least substantially retain conventional water treatment granules therein. The receptacle has a water-receiving compartment with a weir disposed therein to divide the water-receiving compartment into a water inlet sub-compartment and a water outlet sub-compartment with the water inlet sub-compartment sized to receive the hopper loaded with conventional water treatment granules. A water treatment feed system and a method for dissolving conventional water treatment granules in water are also described.
