Rather costly for such simple small raw rock

Small but looks nice in my 10 gallon tank. Kind of expensive for the size. Baught it to try to bring up my ph in the tank. To soon to tell if it worked.

For use in the classroom my students struggled to compare basalt and this limestone because it was so dark. It was only density that helped them distinguish between the two. Pieces are about 1" each.
