Calcium question

[CLYDE'S MOM]

Has anyone used bentonite calcium clay for their sulcatas? I use it for koi fish on their food and in their water, it seems like it might benefit torts too.

I've never heard of it. What makes it better than plain calcium powder? And where do you get it?

Oh, and welcome to the forum! It must be getting cold in your neck of the woods! ?
