Step 1: One Step to Safe Life Giving Survival Water

If you’re using tincture of iodine, use about 2 drops per quart of clear water and 10 drops for cloudy water. Let it stand for at least 30 minutes in order for the iodine to kill the nasties.

Be warned that using tincture of iodine is going to change both the flavor and the color of your water.

The way to eliminate the iodine taste is to add 500mg Vitamin C (Ascorbic Acid). Let this sit for 10 minutes and the excess iodine will drop out of solution which can be decanted or filtered.
