As of 4/20/19
Regeneration times are corrected with no overlap.
Softener has B2 extended 5 to 6 and RR from 10 to 12.
Cleaned toilet reservoirs and installed white test tiles.
Salt and PotPerm filled.

First, it appears the time of day setting was incorrect for K1 tank such that it was overlapping with K2. Probably for the last three weeks.
Also realizing that toilet use during softener regeneration is allowing that bit of insoluble iron trough to interact with chlorine tab in toilet reservoir.
Also also, it could just be the softener needs a bit more B2 or RR so increased B2 from 5 to 6 and RR from 10 to 12.
---Time of day settings now correct and softener timing tweaked and keeping a log for use of master bath toilet.

More testing the next day late afternoon (previous samples were also late afternoon).
Soluble Iron zero
Total Iron also looks like zero
BYPASS softener
Soluble Iron zero
Total Iron about .1ppm.
BYPASS softener, centaur carbon, and second Katalox Light tank
Soluble Iron 7-9ppm
Total Iron not tested
BYPASS softener, centaur carbon, and both Katalox Light tanks
Soluble Iron 9-10ppm
Total Iron not tested
Notes:
Total system is under ideal conditions resulting in no measurable iron
Softener isn't removing much iron
Second Katalox Light tank with Centaur Carbon tank are removing a great deal of iron.
Even with chlorine injection/retention time, calcite tank, and one Katalox Light tank 7-9ppm of iron remain in water.
I would have expected half that number or even less. Is the first Katalox Light tank doing its job?
The second Katalox Light tank and Centaur Carbon tank then remove almost all of that amount with softener doing a small amount of polishing.
As ditto suggested I should: "Backwash the KL tank and see how much iron is coming out during the backwash cycle. Once the water runs clear you should add several minutes after that in the backwash cycle. Be sure to have an adequate rapid rinse cycle."
I should also test the backwash of the softener. If the softener backwash contains iron then the toilet reservoir tank problem could be due to insufficient backwash time and/or use during regeneration?
Below you first see the total iron test of water out of the softener.
Second is the total iron test of water bypassing the softener.
Third is soluble iron test of water bypassing KL2 and Carbon tanks (this result was virtually indistinguishable from the test after bypassing both KL tanks).\
