I bought 2 pieces of "natural rock" slate tile from Home Depot. It was the only thing close to rock they had in the store. there were some slate bricks in the garden area but they were ugly.
We played smashy smashy a bit, which was fun.
It doesn't react to vinegar, and a piece is in a bowl of water to see if it affects pH or turns colours....
Is this safe? Seems safe. Seems like we're doing the right steps to ensure it is safe, we will also boil the rock thoroughly before placing it in the tank.
Any other tests or ideas?
