1. Do I need an independent iron filter system based on the 3.5 ppm iron content? Would a separate media filter such as MediaGuard KDF85 be good, if not, what should I get? Do I go with a smaller softener if iron filter is used?.[/QUOTE]
Answer: I would install an iron filter. Your salt efficiency would be very poor trying to remove that nuch iron along with the hardness not to memtion the wear and tear the softener will suffer wil the iron removal.

Answer: My calculation show you will remove 116,025 grains every 7 days. On an efficiency setting, you would need a 6 CF unit. With a unit that big, you would need to worry about enough flow rate to properly backwash it. You should look at regen every about 3 days with a 3 CF unit.

Answer: Doesn't matter.
.[/QUOTE] 4. Any other help or advice would be appreciated. .[/QUOTE]
Answer: Again, look into getting an iron filter installed before the softener.
