I use a half 1/2 teaspoon per gallon, or 1/2 cup for 55 gallons. That
is for 15 to 20 ppm EIS. I have found that once it goes over 20 ppm, it
will turn milky if you add H2O2. I really have no experience with
anything with that high a ppm, it is too temperamental. I am not sure
what you have, it appears to have a have a mixture of small particle CS
and ionic of maybe 50/50.

Marshall and/or anyone else:
How much H2O2 can you add to CS/EIS and still have EIS?
I ask because I have a brew cell that holds two gallons + a liter and
after brewing I had 28 ppm.
I then added 1/4 cup of H2O2 to convert as much particulate silver to
ionic as possible.
When I did, it turned milky. To get it back to clear, I added almost
four cups of H2O2.
It has a fine Tyndall and is reading 44.3 ppm on my Hanna PWT.
What do I have?
Any help you can give would be greatly appreciated.
