Hello Marshall, I only did the reduction to 60 uS once just to see what happened. While the solution was basically clear, you didn't need a laser to observe the Tyndall effect. A pen light worked fine. As I recall, I had a few larger sparkle particles in the solution.
I didn't keep it very long because I was using it in some soap. Overnight, there was no residue settling on the bottom of the jar, but that was as long as it sat. I regularly reduce a 10 uS solution to a 20 uS solution. This also shows a strong Tyndall effect, is clear, and everything remains in suspension. The main problem I have is not having the equipment to translate uS to PPM.
