Slate in planted tank.
Im starting my adventures in planted tanks with a moderatly lit 10 gallon. I am going to have a short carpet plant in the middle (not sure what yet, but ive got time to hatch that out). Anyway, in the middle of my tank, i am hoping to use slate to make a recreation of stonehenge. Yes, it sounds kinda corny, but i think that it would look really cool. My main question is, would the slate have any adverse effects in a planted tank?
