Do you notice a lot of staining in your tub, toilet and sink? Your ppm seems high to not have a noticeable amount of staining.
I live on the south shore in MA so I know alot about low water ph and high iron content. I have a neutralizer to bring up the PH and a Filox system to remove the Iron and a softener to remove all the hardness added by the neutralizer. I have my own water treatment plant in the basement!!
With that said, do NOT use a softener to remove iron, use an iron removal system, if you are handy you can install one yourself for about $700. I bought mine at cleanwaterstore online, but you can look around. Using a softener to remove iron is a huge waste of money, you have to add salt to the system constantly where as an iron system like my Filox system, it just backwashes every 6 days, and the media lasts over 6-8 years; its an install it and forget it system. I forget my before numbers but post number for maganese and iron are 0 ppm, I love it! Our dishwasher was orange when we first bought the house, it was awful, no staining whatsoever now.
So last year I filled my 30,000 gal 33ft above ground pool over the course of a day and a half. The flow rate and the fact i didn't backwash the system over the course of the fill caused tons of iron to carry over. I wish I took pics but after putting in the chlorine, it turned mud brown. I ran my DE filter for a week straight and backwashed twice a day (one morning I found almost no water flow the filter was so clogged). After the week it was sparkling clear!! For about $100 in electricity (well pump and pool pump combined) $100 in DE, it beat the $900 quoted for pool water delivery. There was some staining at the water line that I scrubbed away easily with magic eraser.
For fill water, the filox system can easily keep up and any iron that gets in the pool will be oxidized by the chlorine, the particles are then removed by the filter. Even without an iron removal system, the chlorine should oxidize the ferrous (or ferric, i forget), and be filtered out.
Any questions let me know, I feel like an expert in this area...
