Hello, I have the following water softener system and would love some help optimizing the programming for salt/water usage, and minimize the number of regenerations. Thanks!

Fleck 7000SXT w/ 32K Grain Capacity
9" x 48" Mineral Tank
14" x 14" x 34" Square Brine Tank
1.00 Cu Ft High-capacity 8% Crosslink Resin
3/4" Noryl NPT Bypass
3/8" Valve-to-BrineTank Tubing
Gravel Underbed
0.25 BLFC

We use roughly 2400 gal/month of water (80 gal/day).
No detectable iron in water.
Hardness is 8-9 GPG.
We use Morton System Saver II pellets.

Here is are some numbers that are probably pretty good. I expect there are improvements that could be made, but your usage is pretty small.

Thanks for your help! One question - the default FM setting that the reseller recommended was t1.5 and instructions said "Do not change this value - this indicated Flow Meter type 3/4" Turbine". What will setting it to t1.2 do instead? Thanks again!

Since that setting is determined by the flow meter, I would go by his setting for that.

The 7000 has a 1.25" turbine meter. The old programming was t1.5, the updated programming is t1.2 (as of a few years ago).

I bought the system in September of 2014, so I'll go with the updated programming. Thanks all for your help!

One more question - I noticed that the Capacity (C) setting recommendation above is for 20K. I have a 32K system, so what are advantages to setting it to the lower 20K setting? Thanks again! I want to learn what all the tricks are as I go.

32 K is based on extremely high salting. This is wasteful and provides no benefits for most applications.
20K is based on lower more efficient salt settings.

You can use 1/3 the salt and get 60% of the same capacity by using the more efficient setting.

Hey, wait a minute.

This is awkward, but...
