ABSTRACT:
The composition and method are for waterways, usually closed cycle, in which algae and the like is to be killed without harm to higher animal life. The composition includes a violet dye to enhance ultraviolet light penetration from the prevailing light to enter the waterway. This ultraviolet light, with reduction in visible light, causes algae death. It also increases free oxygen, neutralizes some toxins, and reduces admission of infrared radiation. The composition includes an enzyme which digests the dead algae and similar material. The products of digestion are such as to leave clean water. A blue dye may optionally be used to hide the violet color of the water in the visible part of the spectrum.
