Based on all of the testing that has been done on Adya Clarity/Themarox from around the world, the product's ability to reduce certain toxic substances [as testing indicates] is based on the amount of Adya Clarity added to the challenge water. It is safe to assume that most questionable fresh water souces such as rivers, wells, tap water, etc, would need between 1 and 2 mL of Adya Clarty per 1 L of water. The safest way to achieve this is through usage of our simple and affordable gravity fed filtration system.
