Has anyone used the Nat'l Geographics substrate? Which way did it alter the pH? I'm not sure if I should keep or return the small bag that I bought.
I've googled like crazy and cannot find out what it is made of. It looks like black sand, but it does not say it is sand. It just says it might alter the pH.
