Abstract
A method of providing a solid oxidizer to a tank of water, while also providing a way to indicate when it is time to add more oxidizer. The preferred method includes providing the solid oxidizer in the form of an oxidizer shell with a coloring agent disposed therein. The coloring agent is substantially color stable when stored in the oxidizer shell, and the oxidizer shell is formed and shaped to enclose the coloring agent in a manner in which the coloring agent is prevented from dispersing into the water until the oxidizer shell is substantially dissolved.
