I went to Home Depot (local hardware store) and went to the landscaping section. I found a slate rock in there that I broke up with a hammer and an extra larger chisel. I then did the vinegar test by placing a piece of the rock into the vinegar. Then I cleaned the rock.

I cleaned the rock by pouring boiling water over it, over and over again. The rock was then cleaned and I placed it into my tank and made an aquascape creation. It was all around 10 bucks!!!

I found that the rock raised my Ph about .5 but it was good because I had a low Ph. But all rock is different.

It won't change any chemistry enough to harm fish. I have quite a bit of it in my cichlid tank and all my fish stayed healthy. Just always test with vinegar to be on the safe side. Rather waste a dollar on vinegar than 500 on live stock.
