A golf ball is provided which changes color or other indicia after significant immersion in water to indicate that the ball has been recovered from a water hazard and may not have predictable flight characteristics which may result in loss of carry and roll. In one embodiment, a microencapsulated dye layer is formed immediately below the final gloss coat, with controlled dye release causing a stained look to the ball after significant immersion in water. In another embodiment, the dye or ink is provided in pelletized form for ease of manufacture. In other embodiments, a dye, ink, or chemical is compounded with other materials and introduced into or applied onto the golf ball's composite materials in a solid, liquid, or gaseous form. In still other embodiments imprints on the ball are made with a water activated ink which either appears or disappears upon the immersion of the golf ball in water.

The present invention is directed to a biocidal water treatment composition, water treatment apparatus, and method of treating water to reduce levels of pathogens. The composition contains sources of copper, zinc, and silver metal ions within a crosslinked polymer matrix. Examples of these ion sources include copper sulfate, zinc sulfate, and silver nitrate. An example of the crosslinked polymer matrix is crosslinked chitosan, which also serves to clarify the water and release the metal ions over time. The product is easy to manufacture, and allows the use of decreased halogen sanitizer, as well as decreased copper ion, thereby decreasing the likelihood of staining. The product simultaneously provides good bactericidal and algaecidal properties, despite low levels of copper ion and low chlorine levels.
