    Water Softner and alkalenity

    My household water has a CH of 250 and a TA of 280. Will a water softner reduce one or both of these numbers?

    It will essentially eliminate the CH.

    It seems to me that it would not have any affect on TA but I don't know for sure.

    A water softener (ion exchange resin) should not change the TA.

    Thanks guys. I knew you would know the answer. Another question: other than cost what are the advantages and disadvantages of using potassium versus salt in a water softner?

    As far as I know, the only advantages to using potassium are:

    1. That it will eliminate the (very slight) salty taste your water may have.
    2. If your discharge line drains into your yard, over time salt accumulation may kill anything growing in that area - but usually that only happens when you're using too much salt for each regen cycle. If it drains into the sewer system, no problem.

    Our discharge comes out salty, but it's been draining into the same part of the yard for over 25 years, and the grass there is alive and well. I really think it's a matter of personal preference.
