Marshall wrote: I believe this is what happened: Initially you had a fair amount of larger particles, the reason it was yellow, and the total ppm was likely over 25 ppm. When you added the H2O2, initially it reacted with the large particles, producing silver hydroxide and silver oxide, which have a solubility limit of about 25 ppm together. So some of the hydroxide and oxide precipitated forming the cloudy part. When you added more H2O2, much of the hydroxide and oxide reformed 2 atom particles, clearing it. Does it change the effectiveness of the CS in any way? Claire
