An automatic non-electric which employs powdered or granular chlorine in a submerged condition and which is operable in response to deactivation followed by activation of the pump of a swimming pool recirculating and water treatment system to automatically inject a given amount of chlorine into the pool return line. This is accomplished by a by pass system which comprises an air tight reservoir for containing treatment solution, a loop of pipe for storage which bypasses a suction line from a swimming pool.
