First of all what are you doing with that chemical

I've been using it in my water softener. I live in a town home and
don't have a separate line for my backyard so the softened water is
used to water my plants. From what I've heard I can only use
potassium chloride since using salt would kill my plants.

My wife has been using softener water, salt re-generation, for the past 14
years with no problems with her flower garden or veggie garden. The amount
of residual salt from a softener is less than normal water content. Check
with your water supply company for normal saline content.
