I have a 13x54 2.5 cu ft softener (80,000 grains) with a Fleck 7000SXT metered control valve on clean city water.

Can someone confirm the Brine Fill settings for me. Is it as simple as configuring C for 80,000 grains and BF for 25 (0.5 BLFC)? Or is that assuming 15 lbs of salt per cu ft and is that wasteful?

1: C Set to 80 (x 1000)
2: RS Set to SF
3: SF Set to 15
4: DO 30 (Max 30 days)
5: B1 Set to 10
6: BD 60 factory set, leave as-is
7: B2 Set to 5
8: RR Set to 10
9: BF set to 25 for 0.5 BLFC

I was thinking that I should use these settings which correspond to 10 lbs of salt per cu ft.

1: C Set to 63 (x 1000)
9: BF set to 17 for 0.5 BLFC

Or 6 lbs of salt per cu ft. Am I on the right track?

1: C Set to 50 (x 1000)
9: BF set to 10 for 0.5 BLFC

I'm not sure how smart the 7000SXT meter is and if it can optimize the regeneration by changing C and BF appropriately. What is recommended?

Thank you

The controller will not do that.

What is your hardness? Just curious. It is not necessary to know to answer your questions, unless hardness is high enough to need further compensation.

I agree with your 10 minute BF and C = 5o for 6 lb/cuft. Your 10 lb/cuft calculation is probably right.

You could use C=60 for 8 lb/cuft, and C=67.5 for 10 lb/cuft.

You can use the variable reserve calculation. Ditttohead points out how it helps save salt.
RS= cr; (cr says base reserve on recent experience)
CR= 0; (0 is default -- leave it)

For further optimization, you can check hardness with your Hach 5B when regen is almost due. Based on what your checks show, you could adjust H up to cause earlier regens and H down to wait longer.

Thank you both.

Reach to answer your question my hardness is 13gpg and 0.3 ppm iron.

I will test out the changes and check hardness from time-to-time.

I am surprised to see 0.3 ppm iron in city water, because city water is chlorinated. That should precipitate the iron out.

Where did the number come from?
