So I need a new water treatment system, had testing done & different quotes with different systems and prices. Have hard water with iron and iron bacteria, sulfur, slight manganese, pH is Ok. .Options : A) Chlorine, retention tank, carbon & softener ( most expensive) B) Hydrogen peroxide, carbon & softener C) Softener with Silica based filter media all one unit & UV light . Had a chlorine system before, the injector would always plug and the retention tank started to leak... Any input on these systems, mostly B and C, thanks
