Our tannin removal resin media comes in 1 cuft bag and works on any form of Tannins that other resin and filter media don't always work. This resin absorbs the soluble tannin that add a foul color and taste to drinking water. Tannin water softener media removes a wide range of metal hydrides and matter from water, while operating a chloride cycle.
Regenerating with salt is much easier. Water hardness is reduced and iron water content should be less than 1 ppm.
