If each tank is 3 cuft, wouldn't 'C' then be 60?C = 40.0 ; capacity in 1000 grains per tank

Thanks. I really thought I had put 60. Edited the known errors out.If each tank is 3 cuft, wouldn't 'C' then be 60?
I think that is dF1b
Not if you want salt efficiency.
IF your BLFC is 0.5 I would use the following. It may not be optimum, but its what I currently think. Let me know if you find mistakes.
I attached a picture
Injector as 3? - Thinking this is the labeled number referenced.
Drain Flow 50 or 30? gpm. The number isn't perfectly legible to me.
The capacity is 96,000 per tank
System info (not programmed)
salt lb/cuft = 6 ; A choice ( efficiency vs capacity)
BLFC = 0.5 ; Brine Refill rate GPM
DLFC = 5 Drain (backwash and RR rate GPM)
cubic ft resin = 3 ; ft3 resin (each tank)
Raw hardness = 85 ; including any compensation
People = 2 ; Does not matter for settings, just forecast
Estimated gal/day = 120 ; 60 gal per person typical calc
Estimated days/regen = 5.1 ; Computed days with reserve
Fleck 9100SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/Upflw, Single Backwash
CT = FI ; Meter Immediate regen trigger
NT = 2 ; Number of tanks
C = 60.0 ; capacity in 1000 grains per tank This would increase the efficiency?
H = 85 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 0 ; can use 0 with CT=FI
DO = 28 ; Day Override (shorter with iron)
RT = 2:00 ; Regen time DOES NOT MATTER since CT=FI
BW = 5 ; Backwash (minutes)
Bd = 60 ; Brine draw minutes
RR = 5 ; Rapid Rinse minutes
BF = 12 ; Brine fill minutes
FM = usually t0.7 ; flow meter,see https://goo.gl/UbWJWW - I have all 3/4" fittings/pipe

Setting it per the settings you suggest changes the current display of gallons remaining from 1017 to 705.
No picture presently attached.I attached a picture
No. The BLFC (Brine Line Flow Control) is a flow restriction device that appears as a black washer with a specific size whole in the centre. It controls the flow rate to refill the brine tank. The injector controls the flow rate of the brine draw from the brine tank as well as the resin slow rinse rate.Injector as 3? - This is the Bflc
Take it easy. No need to roar.

Your prior settings depleted the total capacity of the resin but the initial BF=12 setting, assuming your BLFC is actually 0.5 gpm, only placed enough water in the brine tank to dissolve enough salt to regenerate at the most, 60K grains.My real question is why with the settings I had, that the system cycled through both tanks new and was fine
Hah, bold = roar I guess.Take it easy. No need to roar.
5.0 GPM would make sense for drain flow for drain flow on a 14 inch softener tank. That controls the backwash rate.
BLFC is a different thing: that controls the brine fill rate. Is there another label, I hope?
I think a #3 Injector yellow -- on the graph on page 40 of the 9100 manual shows about 0.49 GPM draw at 40 PSI... That draws the brine from the brine tank by acting as a venturi pump.

That picture is at the drain line (to the floor drain etc), right? Is there maybe another label near the line going to the brine tank? I have never seen a 9100. If there is no label, there are other ways of finding the BLFC value. Asking the seller comes to mind, but there are at least two other ways. This is what the BLFC label looks like on my 5600SXT:The picture is in the #23 comment.
I pulled the float valve part out of the brine tank and didn't see any markings.
The tube that connects the brine tank to the softener, where it connects at the softener is the picture I attached.
12 minutes X 0.5 BLFC = 6 gallons. Each gallon will dissolve 3 lbs of salt so there now would be brine containing 18 lbs of salt.I watched through the brine fill part, it filled the brine tank backup for 12 minutes.
So it sounds as if the brine tank float was blocking things because the water level was so high. Makes sense.The BFLC label says 0.5 GPM. There is a white label and one like yours that I can't make out.
My water seemed like it is getting harder. I had about 18 gallons left with the new settings.
I regenerated it and it never seemed to draw water from the brine tank.
- the cycle started with the water over the float.
- I watched the brine line and the bubbles in it never moved, water level in the brine tank never changed.
When the cycle finished, I took apart both ends of the brine line. All clear.
This cycle started with more brine in the brine tank than normal. If the brine took that long normally, you would increase the BD setting.I siphoned water out of the brine tank until it was a few inches below the float.
Started another regeneration and watched the whole process. Everything seemed to work correctly.
- BD started and counted down from 60.
- Water level hit the top of the air check after about 20 minutes.
8 inches sounds like a lot. I presume there was more than that in there after you siphoned down the brine, so the softener took extra time to suck the brine down.- I watched through the brine fill part, it filled the brine tank backup for 12 minutes.
Now that the cycle is all done, I'd say there's 8" of water in the brine tank.
- Is that enough for a regeneration cycle?
Works. Used up the hot water and now the water is soft. Whoo Hoo!. How nice is that. Thank you very much.So it sounds as if the brine tank float was blocking things because the water level was so high. Makes sense. This cycle started with more brine in the brine tank than normal.

Sounds good, if I am reading things right.
I have a couple more questions.I think that is dF1b

As Bannerman said in post #33, "12 minutes X 0.5 BLFC = 6 gallons. Each gallon will dissolve 3 lbs of salt so there now would be brine containing 18 lbs of salt."1 - I would like to regenrate both tanks completely, the full 96,000 grains each, can you tell me what settings would do that, then I would manually regenerate both tanks and start over fresh with the current settings that have beem suggested.
I think you meant to say 8 lbs/cubic ft of resin.I have a couple more questions.
2 - Does the (BF = 12) setting define the amount of salt used as 6 lbs./gallon? Would changing it BF=19 change my salt to 8 lbs./gallon?
So I can add 9 gallons of water to the brine tank, wait 3 hours or so for it to dissolve salt and then run a regeneration cycle.As Bannerman said in post #33, "12 minutes X 0.5 BLFC = 6 gallons. Each gallon will dissolve 3 lbs of salt so there now would be brine containing 18 lbs of salt."
To regenerate 3 cubic ft from scratch, you need a total of 15*3/3 =15 gallons total. Your last brine fill put in 6 gallons. Thus you would need to add 9 more gallons to do what you like. You can pour that into your brine tank directly without changing your programming. Wait 3 or more hours. Your next regen will use 15 gallons of water plus salt.
As you pour the water, make sure the water level does not rise so high that it will leak out of the place that the brine hose comes in.
After your regen including brine refill, add 9 more gallons again. Wait 3 or more hours before triggering the next regen, or just let it happen when it happens.
I think you meant to say 8 lbs/cubic ft of resin.
19 minutes *0.5*3/3=9.5 pounds per cubic ft of resin.
For 8, you can use BF=16, and in that case, you could use C=72.0.
If you think you are not getting soft-enough water, increase the H number or change RC to 100 from zero.
Yes. That will do what you asked for.So I can add 9 gallons of water to the brine tank, wait 3 hours or so for it to dissolve salt and then run a regeneration cycle.
Repeat for the second tank.
Why? Is the water not soft enough shortly after a regen happens? Is the water not soft enough when it is almost time to do a regen?I think I will change the BF=12 to 16.
I'm gauging the softness via my dishwasher and via my hair in in the shower. Originally I felt that "greasy" feeling on my skin and I don't now. Iam also aware of stiffness of my hair in the same measure. Not anything like when I had pretty much 85 grain hardness to wash with but, off the top o my head I would guess it's between 10-20 now. I will check it with my hach test.Yes. That will do what you asked for.
Why? Is the water not soft enough shortly after a regen happens? Is the water not soft enough when it is almost time to do a regen?
Are you measuring the softness of the softened water, or are you using some other method of gauging softness.
How often does your system regenerate?
This is awkward, but...
