Ok, so the guy at the local landscaping place was nice enough to GIVE me my choice of a small piece of stone for my aquarium. They didnt have any slate but they had this, he called it "blanco" something or other. Can anyone tell me if this will alter my tank water? I will be breaking it into pieces and building terraces and caves from it. I thought it would go nice to add depth (no pun intended) to the tank with jet black eco-complete.
EDIT: Well I dropped it in a bowl of tank water, no immediate reaction. I will test the PH, KH, and GH after it sits for a while.
