I use the medium grain.

Mine is 20/40, think that's medium.

I just changed over to black diamond in medium. I thought the fine and extra fine was way too fine as well. I'm happy with the medium.

Is this stuff safe for dwarf cories?

I used black beauty I believe, and it's about as fine as powdered sugar, and after solid rinsing, it is awesome.

Solid black, but with a sheen, almost crystalline.

Awesome! Thanks guys! Now I know what I'm using next! Does it get stirred up easily like during water change?

20/40 grit not so much as 30/60 grit.
Just don't let the water blast back into the tank, and you should have no problem's.
