Hello:

I have a question regarding setting the capacity and salt settings on
my water softener, with an Autotrol 460i control unit, and 1 cu ft
resin tank. The control unit allows 3 settings: Capacity, Salt, and
Hardness. I'm assuming Hardness is compensated hardness (manual
doesn't say that, but other posts have mentioned using compensated
hardness for the softener setting). The manual has a chart that shows
multiple capacity settings in kilograins and the recommended salt
setting in pounds for each capacity setting. I don't understand what
the capacity setting should be set to. Is this for the total capacity
that we need to have (i.e. the capacity that is calculated based on
the number of people and usage for each person, etc)??? Also, doesn't
the Salt setting need to always be set to 15 lbs for this size resin
tank (1 cu ft)? I read a post mentioning it needs 15 lbs to
regenerate 1 cu ft of resin. The manual shows different salt values
(15, 8, 6) based on the capacity setting used (30, 24, 20), so that
confused me a little, too.

The whole reason I'm checking the settings is we are using much more
water than we used to (mostly from running the dishwasher and washing
machine a lot more, plus adding 2 kids). I have been noticing more
and more that we run out of soft water before each regeneration
cycle. I checked the brine tank and it seems to be clean and no gunk
on the bottom. Next I had our water retested for hardness & iron, and
am checking the settings on the softener.

Thank you very much for the help.
