Well people recommend chlorine shocking your well every two to three years. You also should look into “red out” or “rust remover” rock salt for your softener.
If you shock the well it is gong to take 3 or 4 days of use to clear the well.
Then I would treat the softener two or three times with “Rust Out”

follow the directions on the package it will clean the resin in the softener.
Then used “red out” salt from that time forward.
Do that Rust Out and Chlorine Shock as well as Install an Iron Filter, similar to a Softner but removes Iron.
That is what my dad did for many people years ago, he sold and serviced water softeners and iron filters for 40+ years.
