I found some driftwood by a creek today and i've never gotten any because I didn't feel like paying for it. i've been reading about boiling it to cure it but I was wondering how much it might effect my water quality. I have pretty soft water and I add crushed coral in the filter to add some stability and keep the ph a little bit higher. its only a small piece for a ten gallon, if I boil it really well how low should my ph drop?
