Abstract
A method to control microbial growth and other contaminants present in the water of climate control systems includes using tablets or packets to effectively control the growth of microbes such as fungus, molds, bacteria, and virus present in water for an extended period of time. The tablet or packet formulations include at least two metals and at least one chelating agent. Optionally, more soluble salts are also added to the formulations to induce an initial shock of the biologically active compounds in the water followed by a slower release of the less soluble chelating agents and metals.
