First time poster, long time reader. Thank you all for the valuable info over the years here. I finally have a question, unfortunately it’s been beat to death here already but my math isn’t mathing tonight.



Fleck 2510SXT 96k system capacity(oversized for future human resource expansion with the wife)



38 gpg hardness, 0 iron



Typical usage for a 2 person household



Looking for future proof settings for balance between salt usage and having soft water



What do you experts suggest changing?



-DF/Gal

-VT/dF1b

-CT/Fd

-NT/—-1

-C/96 (this I’m not sure but think lower?)

-H/38 (This if my math is correct should be 46?)

-RS/SF

-SF/15 (thinking of changing this to 7%?)

-DO/14 (I’d like to change this to longer?)

-RT/12:00am

-BW/10

-BD/60

-RR/12

-BF/30(I know this needs changed as well but not sure to what?)

-FM/t0.7

96K is a marketing term for 3 cuft Do not use that for calculations.

Do you know what number/color of injector you have?
Critical-- what BLFC do you have? The 5600SXT commonly has 0.5 gpm, but I don't know if that is the case with 2510SXT

Is this something I can see now that it is installed? I will go look if that is the case.

:edit: Ok, I was able to verify that it is the 0.5 gpm BLFC

Based on my reaserch here I believe I should use:
C- 72
H- 46
BF- 16
SF- 7

SPECIAL System info (not programmed)
salt lb/cuft : 7 ; A choice ( efficiency vs capacity)
BLFC : 0.5 ; Brine Refill rate GPM
cubic ft resin : 3.0 ; Same as (nominal grains/32,000)
Raw hardness : 38.0 ; including iron etc
Estimated gal/day 120.0 ; 60 gal per person typical calc
Est days/regen 12.06 ; presuming days each use reserve capacity


Fleck 2510SXT SPECIAL Settings:
DF = Gal ; Units
VT = 2510 ; Valve type
RF = dF2b ; Downflow, Double Backwash
CT = Fd ; Meter Delayed regen trigger
C = 67 ; capacity in 1000 grains
H = 46 ; Hardness grains after comp factor
RS = rc ; rc says use gallons vs percent
RC = 120 ; Reserve capacity gallons
DO = 30 ; Day Override (typ 28 if no iron/Mn)
RT = 3:00 ; Regen time (default 2 AM)
B1 = 6 ; Backwash 1 (minutes) [3...10]
Bd = 60 ; Brine draw minutes IF injector is #2 blue or #3 yellow
B2 = 4 ; Backwash 2 (minutes)[3...10]
RR = 6 ; Rapid Rinse minutes [5...10]
BF = 14 ; Brine fill minutes
FM = t0/7 (usual) ;
DO = 30 ; Day Override (typ 30 if no iron/Mn)
RT = 2:00 ; Regen time (default 2 AM)
B1 = 5 ; Backwash 1 (minutes) [3...10]
Bd = 60 ; Brine draw minutes
B2 = 4 ; Backwash 2 (minutes)[3...10]
RR = 6 ; Rapid Rinse minutes
BF = 14 ; Brine fill minutes

Is there a benefit to the double backwash as opposed to the single it’s currently set to?

Is there a benefit to the double backwash
Double backwash is most beneficial and recommended when using a lower salt setting that equates to less than 6 lbs per ft3 of resin.

For the recommendation above, the 14-minute BF setting X 0.5 GPM BLFC rate = 7 gallons fill. 7 gallons X 3 lbs salt dissolved per gallon = 21 lbs total to regenerate 67,000 grains usable capacity per cycle.

21 lbs / 3 ft3 = 7 lbs per ft3 of resin. Double backwashing will consume additional water with minimal benefit realized.
