with my silver pulser I do 2 cups for about 2 hrs which is supposed to get me between 5-8 PPM's right? Do you let it go longer to get the higher PPM?
I used a silver pulser and it took about 4 hrs to get to 20 PPM. You can't be sure unless you have some way of measuring the PPM. It's kind of unpredictable how long it will take even if the conditions are all the same.
