Driftwood will reduce pH by leeching tannic acid. Petrified wood is so old it's basically fossilized, I don't think there's much of anything in it. I much prefer the look of petrified wood over the look of rock, somehow it looks more aged and natural (like it's been in the tank forever). I use a lot of it and never seen a change in pH. Some days you're the pigeon and some days you're the statue. Remember that age and treachery will always triumph over youth and ability.

In the petrification process the wood is slowly replaced by a form of silica, usually opal or chalcedony (quartz). Both of which are inert in water.

I use "pH down" to test rocks in this way because it is quite a bit stronger than vinegar so the reaction (fizzing) is a bit more obvious....also because the stuff came in a pH testing kit I bought and I really have no other use for it.
