As I said... And after this I'll let a dead dog die.
I meant to say, you can use a buffer if needed and you can also use crushed coral IF it effects the pH that much.
My response was to simply let the OP know that driftwood can effect pH, as little as it may effect it, it can, the OP asked a simple question.
Driftwood can effect your waters pH, will it? Who knows, my answer is solely based in my experience.
My isn't gold, and its not set on a hill carved in marble.
I stand my ground, driftwood "can" effect pH and that's what the OP wanted to know.
I'll leave this dog dead now, agree to disagree or whatever you wanna call it.
I never said a huge change but again like a broken record was stating the chance is there.
