High iron (12ppm) and high Manganese (.44ppm)and slightly acidic water (6.5)

[Joey_58]

I have a ph of 6.5, iron is at 12ppm, manganese is .44 ppm, hardness is 3 grains, and TDS is 90. I’m trying to figure out which media is the best in my scenario i know birm won’t work because of ph. All the solid magnanese oxides require a higher ph to perform at their full potential. Greensand requires chlorine injection (constant regeneration) or potassium permanganate/chlorine backwash which will require a carbon filter after. So the only other one that I think might be best case would be katalox light. Does anyone have any suggestions?

I don't have expertise in this, but my iron+H2S uses chlorine with regeneration every 3 days. The chlorine gets rinsed out during regen. My iron is much lower than yours, and I have no measurable Mn. So I was not suggesting that my system would be suitable for you.

Your hardness and TDS only barely meets the minimum recommendation for Crystal Right but I think CR100 might be a good choice given the low pH , high iron and Manganese...
