Dr. Dryden's Activate Glass Filter Media

Dr. Howard Dryden is the inventor and founder of Dryden Aqua. For many years, he worked with ocean mammals such as whales, dolphins, and sea lions. For many years he worked with these animals and noticed that they often died at early ages of severe lung infections. Through research, he was able to prove that the air these mammals were breathing located just above the surface of the water is called trichloramines and is the main culprit for giving you the chlorine odor that we all smell in swimming pools. He invented Activate, helping to save the lives of animals by significantly reducing trichloramine formation within chlorinated pool systems.
