Hi Dee, I added the peroxide to the ~25 ppm. brew to reduce particle size although it was only light yellow and possibly deepening in color a little as time was progressing. Adding the H2O2 can put it into the perfectly clear state in a case like this one.
Normal ~10-12 ppm. batches are perfectly clear on their own but when making stronger brews agglomeration begins to occur along with the resultant coulor changes.

Why do you add H202 if I might ask? Is it not clear to start with? dee On 22 Jul 2009, at 12:26, Peter Converse wrote: Hi Marshall and other list members, My EIS was 24 hours old and approximately 25 ppm. It was only slightly yellow but possibly on the way to a deeper shade. I have been able to use 3% food grade H2O2 to clear a ~25 ppm. batch in the past by adding up to one drop per ounce, as I did this time, but in this case I made mud. I didn't want to wait another day to add the peroxide (which I probably should have). I recall that my earlier successes involved a more stabilized EIS, as you suggested; one having sat on the shelf for several days before adding H2O2.
