What color should pulversied limestone be? I used some in my DSB and some of it is black. I don't know enough chemistry to tell if there are any harmful ingrediants in the bag(I bought from home depot) but I assumed it would be okay.
I was looking at another thread where someone had a picture of their DSB of pulverised limestone and the color was grey/white.
Do I have reason to be afraid because of the dark color of my limestone?
