That's an easy number to work with, so let's use it. 20 drops/milliliter = 20,000 drops/liter =1,000,000 drops / 50 liters. That means one part per million is the same as one drop of a substance in a million drops, or 50 liters, of water.
Take a liter bottle, divide it into 8 equal parts. Mix 24 drops of MMS and 24 drops of 50% citric acid. Swirl or mix for about 20 seconds. Fill the bottle with water and you will have a 3 drops of MMS activated per line taken hourly. NOTE: This activated bottle of MMS will last up to 5 days in the fridge.
