Natural stone effect on water chemistry?

We are looking at installing large natural (Tennessee stone) rock water features in our pool. I have read that this will throw off water chemistry and require significant amounts of muratic acid. Can anyone shed some light on this?

Some natural stones contain iron. Be sure anything you use does not have that.
Yep.. Here is my lesson learned.. It does scrub off with acid and has never caused additional issues...

As far as the pH is concerned, few glugs of acid every other day is all that is required. We really love the waterfall so it is a very small price to pay in our view... IMG_20190330_112234.jpg

I never has staining or Iron until we have our Tile coping replaced with Stone. Now that I know what it is and the cause I just added jacks Pink stuff every once in a while..
Can you seal the stone?
