I have watched a number of YouTube videos dealing with CALPHOS (vinegar and eggshells). Given that vinegar is also used for plant killer, how worried do we need to be about using CALPHOS in quantity? The videos seem to use just a little CALPHOS with
water. I'd like to make and use about 5 gallons as I have a lot of eggshells. So...moderation in all things I guess but I'm wondering how concentrated I can push and how much I can use without being terribly concerned.
