1. The first unit below removes tannins, softeners the water (removes hardness) and small amounts of iron.
2. The second unit is the tannin eradicator and it removes hardness, clear iron, red iron, manganese, tannins, medals, hydrogen sulfide and controls the build up of bacteria, algae, and fungus.
Tannins give the water a yellowish tea color and can only be removed with special resin media.
These systems remove tannins, hardness, and iron. Some will remove clear iron, red iron, manganese, metals, hydrogen sulfide, and will control the build up of bacteria, algae, and fungus.
Note: Some water may still require iron filter
