A swimming
pool chlorinator that utilizes a cylindrical housing that has an internal chamber. Within the internal chamber is concentrically mounted in a close fitting manner a valve member. The sidewall of the housing has a series of elongated slits and also the valve member has a series of similar elongated slits. The housing has mounted thereon at least one suction cup with the suction cup to be securable to a swimming
pool wall surface or other surfaces associated with a swimming
pool and beneath the surface of the water in the pool. Within the internal chamber of the housing is located one or more
chlorine tablets. The valve member is to be adjusted relative to the housing so that the slits of the housing are unrestricted permitting
free flow of water through the housing or the slits are restricted partially thereby limiting the amount of flow of water through the internal chamber. As the water is conducted through the internal chamber, the
chlorine tablet is dissolved within the water which chlorinates the water of the swimming pool when this water is conducted exteriorly of the housing.
