I use the iron-removing stuff- usually about $13/bag or more locally .

Good reminder- I just put in my last 4 bags. Got caught short one time during Covid, and had to pay the Culligan guy $18/bag. But he had it.

I'll pick up 4 more bags today at the big box store - I like a reserve of at least 2 at all times since then. It doesn't spoil.
