George, I know you are fascinated with Physics etc. Take one or two courses in Physics: Optics, Thermodynamics, Particle Physics etc. etc. I am sure infrared, near infrared all will be clarified. I think there is a university: University of Puerto Rico in your area.
I am not in a position to clarify: "Sun vs. Momotaro radiating ceramic beads" in clearing pond water. I think Physics department/ UPR will be able to do that a lot better.
