Aqua-mandix is a natural, crushed manganese dioxide without additives and free from contamination. Used as a joker for catalytic removal of dissolved iron and manganese in one filtration step. The product will do a very good job already at pH 6,5 and even in presence of NH4. Aqua-mandix will also remove "parts of" As, Al and H2S if present next to Fe and Mn.

passes its activity on to the surrounding sand grains,
does not require ideal pH environment,
does not require regeneration by KMnO4.
works even in presence of NH4
