water treatment for acidic water with iron and manganese

looking for suggestions on what treatment system to use. 350 foot deep well in new england. 3 baths, 2 adults and two teenagers who take long showers. pH 6.0 TDS 150 ppm Hardness 70 ppm color 45 units iron 1.7 ppm manganese 0.2 ppm copper ND nitrates 0.3 ppm sulfate 7 ppm sodium 49 ppm tannis ND
lots of red brown ppt in sediment filter.
different vendors have suggested different treatment methods. some suggest AN filter with a softener, others AN with aeration followed by a backwashing filter bed.
thanks in advance for your suggestins

The AN filter and aeration/filtration won't remove the natrual hardness (4.09gpg) nor the added hardness (7±gpg) from the AN filter. That equipment will cost much more than an AN filter and then a properly sized softener with the right type of resin. Which IMO is the only way to go, and the AN filter should be a backwashed model, an upflow model isn't going to work right for very long; unless they prefilter and then you'll be changing cartridges frequently and suffering pressure loss until you do. Plus that pressure loss will prevent the filter after the aeration from backwashing properly (IMO). Email me if you want sizes and prices and would install it yourself or hire it done. Or to compare the sizes and prices you've been given.
