IME, driftwood doesn't reduce pH by much - and that's despite a KH of 2° and minimally rinsing the wood (usually goes into the tank on the same day).Ok thanks so if my ph was neutral what would it lower it to roughly?
I agree. I forgot to mention that before. IMO, a piece of driftwood is going to always leak a little bit of tannis. That's not an issue for me though.I've found that only driftwood that is currently leeching tannis will lower pH. Even then, it is not significant enough really affect the pH.
That is my experience.
