"Can faintly see a red line at normal ambient light. Is this good or bad or just is?"
That is very good as it indicates that you are making actual silver particles as well as ions. "I just realized that I was only shinning the light through the 15 ppm jar and not the 0.8 ppm (bubbler only) jar. SS" You should not see a line in this unless dust particles have been introduced in the bubbling process. Your next step would be to let the process run and see how strong the laser beam becomes before the solution becomes slightly yellow, indicating a particle size in excess of 40nm, which is these days deemed undesirable. Not too many years ago, before we had access to lasers and ppm meters, we ran the process until we had a yellow tinge, as that was the only way that we knew that we were done.
