Thank you, I truly appreciate it! I will take you up on that offer! I'm waiting on a Hach 5B to arrive so I can get exact numbers. I have a 48K unit with an 18x33 salt tank. I'm on well water with no iron. The paper strip showed a hardness of 6, which seems low.
For now I have these settings (found in a you tube video):
df: GAL
vt: df1b
ct: Fd
NT:1
c: 48
H: 7
RS: rc
RC:150
DO: 7
RT: 2:30
BW:10
BD: 60
RR: 10
BF: 10
FM: t0.7

A 48,000 grain Capacity setting is too high as regenerating 100% capacity would be highly wasteful and inefficient. To regenerate 48K Capacity, would require 30 lbs salt each cycle, resulting in a Hardness Efficiency of only 1,600 grains/lb (48,000 / 30 lbs). Your current 10-minute Brine Fill setting X 0.5 gpm BLFC = 5 gallons entering the brine tank, which will result in 15 lbs salt becoming dissolved.
To substantially increase efficiency, the usual recommended Capacity setting for a 48K softener will cause regeneration to occur when no more than 36K grains capacity has been consumed. This lower Capacity setting will require only 12 lbs salt each cycle, thereby increasing efficiency to 3,000 gr/lb.
To reduce the salt setting to 12 lbs, reduce the BF setting to 8-minutes.
Testing Hardness with test strips is not recommended as results are not usually accurate. A Hach 5B Total Hardness test kit utilizes chemical titration to accutately identify each 1 grain per gallon of total hardness.
You currently have Reserve capacity programmed as 150-gallons.
The Reserve Capacity setting should represent 1-day average soft water useage.
If 2 people reside there, a 150-gallon reserve setting should be appropriate, but if there are additional residents, then the reserve setting will likely need to be increased.

Thank you for the advice. Clearly, I will need to adjust once the Hach 5B kit arrives
System info (not programmed)
salt lb/cuft = 7 ; A choice ( efficiency vs capacity)
BLFC = 0.5 ; Brine Refill rate GPM
cubic ft resin = 1.5 ; ft3 resin = (nominal grains)/32,000
Compensated hardness = 8 ; including any compensation
People = 2 ; gallons affects reserve calc
Estimated gal/day = 120 ; 60 gal per person typical calc
Estimated days/regen = 34.44 ; Computed days including reserve
Fleck 5600SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/, Single Backwash, black cam
CT = Fd ; Meter Delayed regen trigger
NT = 1 ; Number of tanks
C = 33.1 ; capacity in 1000 grains
H = 8 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 120 ; Reserve capacity gallons
DO = 30 ; Day Override (28 to 30 if no iron)
RT = 2:00 ; Regen time (default 2 AM)
BW = 5 ; Backwash (minutes)
Bd = 60 ; Brine draw minutes
RR = 5 ; Rapid Rinse minutes
BF = 7 ; Brine fill minutes
FM = ____0.7 ; https://terrylove.com/forums/index.php?attachments/img_fleck5600sxt_flow-png.31592/
If not 2 people, increase/decrease RC by 60 per person

Thank you so much! It's four people, so RC 240 and everything else the same?
Yes.

Your original settings, caused regeneration to be delayed until all 48,000 grains of resin capacity was depleted, but your BF setting & BLFC resulted in only 15 lbs of salt being dissolved, which is sufficient to regenerate only 39,000 grains of capacity.
The 9K grains or depleted capacity, is not providing any hardness reduction benefit, so hardness leakage will be greater than is necessary.
To regenerate the 9,000 grains of depleted resin capacity, as a 1X procedure, after reprogramming the controller as recommended above, perform 2 manual regenerations back-to-back with preferably none or at least minimal soft water utilized in between the 2 cycles.
If you initiate the 1st regen cycle about 2 hrs before you normally retire for the evening, it should be fully completed after approx 1.5 hrs.
Wait about 30+ minutes before initiating the 2nd cycle, which will permit sufficient time for salt to dissolve for the 2nd cycle. The 2nd cycle can then continue after you retire, thereby resulting in the availability of high quality soft water in the morning and thereafter.

Great tip, thank you!
