Hello - I recently had a katalox and carbon filter installed to take care of iron and manganese (7 ppm and .35 ppm). Also some sulfur odor. I have a 120 gallon contact tank, then the carbon filter, then the katalox filter. I have a bout .8ppm residual chlorine after the contact tank.
Should the installer have put the katalox filter first before the carbon tank? Everything does seem to be working as is.
