Pro-Ox Iron Filter followed by a water softener is a great way to remove iron, manganese and hardness from well water with very little maintenance required. To keep the Pro-OX media clean and free of iron bacteria build-up, a chlorine side tank can be used. During backwash a small amount of chlorine bleach is sucked into the tank which keeps the media clean. No chlorine gets into the house water in this process. Just add some chlorine bleach and a little water softener salt every few months!
