Abstract: The present invention relates generally to novel water treatment compositions. More particularly, the invention relates to solid water treatment compositions in the form of a water soluble tablet containing at least one halogen source and at least a pH compensating source in a layered tablet in which each of layer is configured to be simultaneously exposed to the water being treated and wherein one layer comprises the halogen source and another layer comprises a pH compensating source. Methods for controlling water biofouling and disinfecting water systems, particularly swimming pools and spas, are disclosed.

Abstract: The present invention provides several embodiments of a device for automatically feeding soluble fluid treating agents in both tablet and granular form into a fluid body such as a swimming pool, spa or toilet bowl tank. Each embodiment includes a holding member for holding the soluble fluid treating agents which is selectively moveable along at least a portion of the length of a shaft member so as to adjustably position the soluble fluid treating agents relative to the fluid body. The shaft member is removably attachable to a base member that holds the device in operative position. The holding member can be selectively positioned such that any portion of the soluble fluid treating agents can be immersed within the fluid body. When a plurality of tablets are utilized, the holding member includes an elongate portion and each tablet preferably includes an opening extending therethrough adaptable for receiving the elongate portion.

Abstract: A device for automatically feeding soluble fluid treating agents in tablet form into a fluid body having an elongated member, a platform member adaptable for holding a plurality of tablets and being selectively positionable relative to the fluid body, and an attachment mechanism for attaching the present device to a portion of the structure surrounding or containing the fluid body. When a plurality of tablets are loaded onto the platform member, the platform member can be selectively positioned such that any portion of one or more of the plurality of tablets can be immersed within the fluid body. Each tablet preferably includes an opening extending therethrough adaptable for receiving the elongated member, the present device having particular utility in a wide variety of different fluid treating applications including toilet bowl tank applications and swimming pool/spa applications.
