PH shifts due to rock are always a frequent question. Folks who sell products will tell you their product may help buffer water. My personal opinion is that it takes water a rea y long time to dissolve rocks. I figure if nature cannot dissolve the rocks in a couple hundred thousand years, they will last long enough for me not to notice them dissolving in my tank. That is really making is sound simple but rocks are petty simple. I would watch for PH shifts any time something new is added but I never worry about it. source

I've heard that, but as far as being aware of any "fact" about the fossil record, I'm clueless. I just read different stuff and am stuck with the opinions of others as I've never dug up, dated, or analyzed any fossils myself.
