Abstract: A method of maintaining a safe free chlorine level in a body of water for recreational use where the free chlorine level at a harmful level comprises determining if the free chlorine level in the body of water is above a safe level and adding sufficient DMH to the body of water to bring the free chlorine down to a safe level.

Abstract: A method and device for maintaining a body of water in a sanitized condition wherein the body of water is free from a source of bicidal metal ions and free from bromide or bromine compounds that can sanitize the body of water, the method including that steps of maintaining a chlorine level in the body of water at a level of between 1 ppm and 1.0 ppm; introducing a non-chlorine based oxidizing agent into the body of water wherein the chlorine level in combination with the oxidizing agent is selected so as to be insufficient to sanitize the body of water, and introducing a compound having a hydantoin ring therein into the body of water whereby the combination of the chlorine and the oxidizing agent sanitize the body of water without the presence of a source of biocidal metal ions to supplement the chlorine.

Abstract: A system, a cartridge and a dispensing valve for eliminating a drift or sag in BCDMH output from an inline dispensing valve containing a dispensing cartridge mountable within the inline dispensing valve with the dispensing cartridge containing a batch of water erodible cluster inhibiting BCDMH particles to provide a linear output flow of BCDMH which is responsive to flow of water though a cartridge in the dispensing valve and a method of obtaining a linear output in a dispensing system by increasing the size of particles in a dispensing cartridge in the system.

Abstract: A method of maintaining a safe free chlorine level in a body of water for recreational use where the free chlorine level at a harmful level comprises determining if the free chlorine level in the body of water is above a safe level and adding sufficient DMH to the body of water to bring the free chorine down to a safe level.

Abstract: A method of assisting a customer to obtain water care information and products by associating the customer with water care dealer through a supplier-associated app where the water care dealer is identifiable through a QR Code.
