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.

If you dumped the backwash it would but the amount of salt actually in the
water is infinitesimal. The salt is used in the regeneration, not the
normal flow mode.
