Abstract: An improved apparatus 10 and corresponding methods for in-situ application of chemical in a swimming pool or spa or the like. Apparatus 10 generally has a handle receiving portion 50, a handle receiving base 90 to which the handle receiving portion 50 is attached, and at least one securing component 11, 13, or 14. The at least one securing component is made of suitable material (i.e. soft, flexible, bendable, twistable material such as strap, wire, twine, string, or the like) to allow adjustment to surroundingly secure around any size and/or shape container 60. One form of the at least one securing component is straps 11. The straps 11 are inserted and secured near receiving slots 92, and they are placed and surroundingly secured around the container 60. The ends 22 and 24 are secured to the base 90 by folding over an end piece 19 of each strap 11 so that VELCRO.TM. hook and loop fastener material 15 located on the underside of each end piece 19 engages and attaches to VELCRO.TM.

Abstract: An apparatus 10 or 15 and corresponding methods for applying chemical/acid wash solution 65 from a container 60 in a swimming pool/spa 100 to clean and remove stains, scale deposits, and the like from desired areas. The apparatus 10 or 15 generally has a frame 11 or 12 for receiving and holding the container 60 and a handle receiving portion 50 for attaching a handle/pole 40 to allow a user to grasp and move the apparatus 10 or 15 within the pool/spa 100 and to allow chemical/acid wash solution 65 to flow to desired areas. In one embodiment, frame 11 is made of tubular material and has a rectangular base 20 and a rectangular U-shaped brace portion 30. In another embodiment, frame 12 has two half portions 70 and 80. Frame 12 is generally made of a vinyl coated wire construction, and half portions 70 and 80 are generally semi-cylindrical vinyl coated wire structures. The half portions 70 and 80 are hingedly attached to each other so that the frame 12 can be moved between an open and closed position.

Abstract: This invention discloses a device that provides the most effective means or method of dispensing a strong stabilized such as Chlorine or Bromine in the form of tablets, stick or granules to sanitize water in a contained vessel such as swimming pool, spa, or in a recirculating water system such as cooling tower, fountain, or water reservoir. This device contains stabilized chlorine or bromine tablets, sticks or granules, and sinks to the bottom of the water contained vessel. There it release chlorine or bromine into the water from the bottom of the water containing vessel without losing any chlorine or bromine into the atmosphere.

Abstract: This invention discloses an in-situ process or method for cleaning the interior surfaces of a swimming pool or the like for removing stains, scale, calcium deposits, and the like, and without the need for draining the pool. The chlorine content of the pool is initially tested, and chlorine is added to bring it up to a level sufficient to prevent algae growth for a period of up to 10 days without filtering. Water is added to the pool to insure all water line marks are sufficiently immersed so as to benefit from the cleaning operation. An acid wash solution, including a mixture of hydrochloric acid and a strong metal chelating agent, is then applied in-situ or as close to the surfaces to be cleaned as possible. As the stains, scale, and deposits dissolve, a strong organic acid such as oxalic acid is added to precipitate out the undesirable materials and cause them to settle down to the bottom of the pool for subsequent vacumming.
