Dispenser for water treating agents

A water treating agent dispenser for dispensing solid or liquid water-conditioning/treating agents into a body of water;

• the dispenser comprising a hollow body;
• having an overall specific gravity such that, when said hollow body is substantially empty of water-conditioning/treating agent(s), the hollow body will float, but when the hollow body contains water-conditioning/treating agents, the hollow body will sink;
• said hollow body comprising:
• an inner surface and an outer surface;
• a plurality of openings formed in said body;
• said openings extending from said outer surface to said inner surface to place an interior of said body in communication with an exterior of said body;
• and
• an axial positioner and a radial positioner;
• said axial and radial positioners extending from said inner surface of said body and being sized, shaped and positioned to maintain the water treating agent within the body, to position the solid water treating agent spaced from the inner surface of said body, and to allow water to contact all sides of said water treating agent;
• wherein,
• (a) said axial positioner comprises a plurality of ribs extending from said inner surface of said body;
• said axial positioner ribs having an axially extending edge which is generally parallel to said axis of said body;
• and
• (b) said radial positioner defines a support surface which is generally perpendicular to said axis and is spaced from said inner surface of said body;
• said support surface being shaped to allow water to contact ends of said solid water treating agent.
