What regarding PH? It's quite common knowledge amongst FH keepers that (regardless of the exact mix of species making up an individual FH) they'll get better grooming results in a higher PH (e.g. 7.9-8.2). By better grooming I mean bigger kok (esp. in ZZ Dragons), brighter pearls and better red coloration -- I've seen it myself keeping them for well over a decade. A quick Google search and perusal of some FH forums will substantiate my experience.
If you are referring to the driftwood's effect on PH well of course that will depend on how much it's cured and also type of wood it is, but as a generality most FH keepers (esp. with show quality FH's) don't keep driftwood in their tank because of this and also possibility the FH will injure itself on the driftwood.
