Dealing with Iron in Arkansas

Hi everybody! I have 10ppm plus iron! I currently use chlorine injection, a calcite/corosex tank (Fleck 5600), a centaur carbon tank (Fleck 5600), a MTM tank (Fleck 7000), and a water softener (Fleck 6600). All mineral tanks are 10x47 with 1" riser tubes and top distributor baskets. My MTM tank has a fine mesh riser tube and top distributor basket. My well pump generates about 8 gpm.
Here are various notes I'll organize:

November 18, 2007:
My 5-in1 test strips reveal:
A pH of 8+
Total Alkalinity of 240 ppm (there's definitely some blue there suggesting 180+)
Total Hardness of about 0
And no total or free chlorine
A Hach Total Iron test strip result of 0 ppm
A phenol red test reveals a pH of 8+
My pH in is about 6.3, after calcite it was 6.8, and after calcite/corosex it is around 8
I just tested with a strip and it looks like Total Alkalinity ppm (CaCO3) is 180 to 240.
I noticed just a few minutes ago that only 245 gallons are left before regeneration of the water softener.
Normally my Total Alkalinity is closer to 120.
My water hardness was reading 120 and normally it looks close to zero.
Maybe I need to tweak the softener regen settings?
The pH was purple as can be, 8.4+?

MTM valve should be set to:
Cycle 1 - 10
Cycle 2 - 45
Cycle 3 - 10
Cycle 4 - 10
Cycle 5 - 10 (you have a 0.25gpm BLFC)

Fleck 7000 valve on my MTM tank set at 15 and the capacity at 24 and the regeneration settings at 10/45/10/10/10. See above.

Two 40 gallon retention tanks and a 47 gallon pressure tank. I assume this works out to be around 100 gallons of retention. My well pump maximally kicks out 8 gpm.

I use Dow Corning 7 Release Compound:

I'm interested in Vortech bottom distributor plates:

Am I using
Pur-Gard?
Notes:You definitely can shock your brine tank with Pur-Gard.
Pour 1/2 a bottle of Pur-Gard into your brine tank via the brine well.
Allow at least 1 hour of contact time & then regenerate the system within 12 hours.
After that, pour the balance into the feeder with the existing res-up.
Top up with Pur-Gard from now on and life is good.
The drip-feeder does indeed cause dilution, so I'd suggest you shock the tank about once a year for total peace of mind.
