Thanks, newcan1. I asked myself many times in the past 10 years if I should toss my Hydroxylamine Sulfate and CD-4. Glad that I did not actually let go the stuff. Never thought I would ever use it. Based on your message I probably need to increase the dosage of CD-4 to about 5.5 grams per liter of water. Hope to get to try it in the next few days.
