Abstract: A floating dispenser holder having a platform supporting a dispensing cartridge in a dispensing condition and a canopy extending over the dispensing cartridge located on the platform.

Abstract: A method of reducing the cyanuric acid in a body of recreational water by adding an algaecide such as metal ions to the body of recreational water before reducing the chlorine content in the body of recreational water followed by adding a cyanuric acid reducing agent to the body of recreational water to generate byproducts where the addition of chlorine can be used to remove the byproducts from the body of recreational water before adding additional chlorine to establish a safe level of chlorine in the body of recreational water.

Abstract: A method of maintaining a body of water in a usable condition where a sensor located in the body of water transmits information on water conditions to a server with the server including a database with the server generating a first maintenance recommendation if it is determined that the body of water contains a synergistic chemical combination and a different recommendation if it is determined that the body of water does not contain a synergistic chemical combination even though the transmitted information on the water conditions are the same.

Abstract: A method and dispenser for maintaining a body of water in a swimming pool free of algae with the dispenser water mateable to a surface within a skimmer basket to deliver at least one dispersant to the pool water flowing through the skimmer basket.

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 dispenser for maintaining a body of water in a swimming pool free of algae with the dispenser water mateable to a surface within a skimmer basket to deliver at least one dispersant to the pool water flowing through the skimmer basket.

Abstract: A method and dispenser for maintaining a body of water in a swimming pool free of algae with the dispenser water mateable to a surface within a pool pump basket to deliver at least one dispersant to the pool water flowing through the pool pump basket.

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 dispenser securable in a hostile environment of a body of recreational water with the dispenser having a dispersant chamber with a dispersant therein isolated from the hostile water environment proximate the dispenser to enable dispenser placement in various locations within the body of recreational water without adversely affecting a dispenser dispersant rate.

Abstract: Systems and methods for trusted gaming transactions using blockchain technology, including creating a smart contract defining terms of a particular gaming transaction using a blockchain, activating the smart contract once a threshold amount of game tokens are purchased by participants, and providing a secure game token transferring interface and platform configured to utilize a blockchain protocol to verify ownership and authenticity of the game tokens prior to enabling transferring of the game token from one participant to another participant. A status of the event is monitored using the smart contract, and a payout is initiated to a digital wallet of one or more winning participants by the smart contract upon the occurrence or non-occurrence of a triggering event.

Abstract: A filterwell cartridge having ports for dispensing a dispersant directly into a filterwell of a hot tub, spa or the like with the filterwell cartridge peripherally and postionally supportable in a quick release mode through facial engagement of compound surfaces located on opposite sides of the filterwell cartridge.

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 filter well mountable dispenser holder securable within a hot tub filter well with the dispenser holder supporting replaceable dispersant containing dispensing cartridges positionable within a circulating flow of water through the filter well to thereby release dispersants therefrom without preventing the circulating flow of water from passing through the filter media proximate the dispensing cartridges.

Abstract: A two-part dispensing device for a pool having a dispensing saddle with a static port therein for continual delivery of a first dispersant and a hold for floatingly supporting itself and an exchangeable dispensing pod therein with the dispensing pod having a dynamic port and a static port for a continual delivery of a dispersant wherein the static port delivery of a dispersant maintains the pool at a safe level when there is no human bather load on the pool and the condition of the disperant in the dispensing pod can be determined by the orientation of the dispensing saddle and the dispensing pod in the pool.

Abstract: A method of maintaining a body of water in a usable condition through a comparative measurements of total chlorine and free chlorine in the body of water to determine if a synergistic chemical combination exists within the body of water that can effect the amount of chlorine to add to the body of water.

Abstract: A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.
