Abstract A pellet magazine in which solid water-soluble chlorine pellets are stacked is connected by a secondary line to the return line of a conventional pool water recirculation system downstream of the recirculation pump. The water flows upwardly into the pellet magazine to wet some of the pellets. A venturi unit farther downstream of the return line creates suction to draw chlorine solution from the wetted pellets through one leg of a U-shaped suction tube having another leg suspended in the pellet magazine. The tube leg is vertically movable within the magazine. Its inlet end can thus be at any desired level to control the amount of water in contact with the pellets. Treated liquid flow is from the downstream portion of the return line into the pellet magazine and thence through the suction tube and the venturi back into the return line to be mixed for presentation to the pool.
Apparatus in accordance with claim 1 wherein the magazine comprises a primary vertical cylinder adapted to contain vertically stacked water soluble solid chlorine, and a secondary vertical cylinder adapted to receive one leg of the U-tube, said secondary cylinder being open to the primary cylinder along their common vertical extent.
