i think i got a good deal today - $10 for 20 3x3" tiles cut from a 16x16" black slate tile. the manager was going to charge me twice as much, but i lucked out.
anyway, my question is: is black slate aquarium safe. i think it is, but just wanted to make sure.
while we're on the topic of aquarium safe rocks, are green slate and rainbow slate safe as well?
