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.
Claims26
A method of reducing cyanuric acid in a body of recreational water containing an amount of chlorine effective for maintaining the body of recreational water in a sanitized condition for human use, comprising the steps of:
- adding a source of metal ions to the body of recreational water to inhibit growth of algae in the body of recreational water and in response to an amount of cyanuric acid in the body of recreational water being high enough to render the amount of chlorine in the body of recreational water ineffective for maintaining the body of recreational water in the sanitized condition for human use, wherein the source of metal ions comprises a source of silver ions;
- adding a chlorine neutralizing agent to the body of recreational water to substantially eliminate the amount of chlorine in the body of recreational water followed by adding a cyanuric acid reducing agent to the body of recreational water;
- allowing the body of recreational water to rest while the cyanuric acid reducing agent hydrolyzes the cyanuric acid and forms biuret in the body of recreational water, thereby reducing the cyanuric acid in the body of recreational water;
- and
- adding sufficient chlorine to the body of recreational water to remove the biuret and to restore the amount of chlorine in the body of recreational water such that the body of recreational water is in the sanitized condition for human use.
A kit for reducing cyanuric acid in a body of water containing chlorine, comprising;
- a first container containing a source of metal ions therein, wherein the source of metal ions comprises a source of silver ions for inhibiting growth of algae in the body of water;
- a second container containing a chlorine neutralizing agent for substantially eliminating chlorine in the body of water;
- and
- a third container containing a cyanuric acid reducing agent for hydrolyzing the cyanuric acid and forming biuret in the body of water, thereby reducing an amount of cyanuric acid in the body of water.
A method of reducing cyanuric acid in a body of recreational water containing chlorine, comprising the steps of:
- first adding a non-chlorine algaecide to the body of recreational water to inhibit growth of algae in the body of recreational water, wherein the non-chlorine algaecide comprises a source of silver ions;
- second adding a chlorine neutralizing agent to substantially eliminate chlorine in the body of recreational water;
- third before adding a cyanuric acid reducing agent to the body of recreational water, which includes cyanuric acid;
- fourth allowing the body of recreational water containing the cyanuric acid reducing agent to rest as the cyanuric acid reducing agent hydrolyzes the cyanuric acid, thereby reducing an amount of cyanuric acid in the body of recreational water and forming a cyanuric acid metabolite;
- and
- fifth adding chlorine to the body of recreational water to remove the cyanuric acid metabolite.
