Why do you add H202 if I might ask? Is it not clear to start with? dee

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.
