Just moved update water softener settings

[My city water]

Hello all

We recently moved and I wanted to confirm my softener settings. We have 4 adults in the house and averaged 800-1000 gal of water a month. The city water hardness here is between 18-21. I tested it this morning with my hatch kit and it was 21 (Thank you central Texas)

Here’s the system
FLECK 9100 3/4 TWIN ALT METER SXT
48000 GRAIN WATER SOFTENER SYSTEM with: 9100SXT electronic metered twin alternating control valve
2-10x54 Fiberglass Resin Tanks,
3 Cu Ft High Capacity Resin ( 10% Chlorine Resistant)
Gravel Under bedding,
18x33 brine tank

My current settings
Vt dF1b
Ct fl
Nt 2
Ts u1
C 24
H 24
Rs RC
RC 0
Do 21
Rt 2:00
Bw 5
Bd 60
Rr 5
Bf 6
Fm t0.7

Should I increase C to 30? Also for the initial start what’s the recommended amount of water to add to the brine tank? Is 2 gal enough? At our previous house as the salt got to 30 lbs or so I had about 2 extra inch of water. I’m assuming I just didn’t have enough salt in the tank.

Increase H for high-hardness compensation.

System info (not programmed)
salt lb/cuft = 8 ; A choice ( efficiency vs capacity)
BLFC = 0.5 ; Brine Refill rate GPM
DLFC = 2.4 ; Drain (backwash and RR rate GPM)
cubic ft resin = 1.5 ; ft3 resin (each tank)
Compensated hardness = 24 ; including any compensation
People = 3 ; Does not matter for settings, just forecast
Estimated gal/day = 180 ; 60 gal per person typical calc
Estimated days/regen = 8.3 ; Computed days with reserve

Fleck 9100SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/Upflw, Single Backwash
CT = FI ; FI=Meter Immediate,Fd=Delayed regen
NT = 2 ; Number of tanks
C = 36.0 ; capacity in 1000 grains per tank
H = 24 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 0 ; Can use 0 for no reserve
DO = 28 ; Day Override (shorter with iron)
RT = 2:00 ; Regen time matters after DO days or CT=Fd
BW = 5 ; Backwash (minutes)
Bd = 60 ; Brine draw minutes
RR = 5 ; Rapid Rinse minutes
BF = 8 ; Brine fill minutes
FM = usually t0.7 ; flow meter,see https://goo.gl/UbWJWW

BF of 6 (what you use currently, 7 or 8 are all good choices.
