Driftwood and pH levels?

In one of my 10 gallon tank, I have a piece of driftwood that about 12 inches long, and 2 inches wide.

So driftwood will change the pH, but how long does it take to do so, and how significant is the change?

If I keep doing water changes, the pH change that I have accumulated will go back to regular tap water pH right?Driftwood and pH levels?
';Make sure the wood came from fresh waters containing no salt or pollution. Quite often the wood will cause the water to turn yellow and drop the pH. If this occurs, transfer the wood to a bucket and make frequent water changes until the wood has nothing left to give. Make sure there are no other factors in the quarantine tank that may lead to such changes in water chemistry. If all looks good, try adding a fish to the aquarium. If the driftwood was found dried out you may need to anchor it down in the tank with large rocks. Remember to scrub even store bought wood clean with a strong brush before introducing it to any aquarium.'; Happy Fish keeping';Driftwood and pH levels?
Driftwood in your tank, leeches, as the term is called, tannins into your water. This directly effects your PH, and your hardness buffer. Typically, as your hardness drops, so will your PH. This is what driftwood does to your PH.



How long it will take is going to vary on several factors, among them being, the volume, the relative PH and hardness in the tank, and the overall size of driftwood in the water. Each tank is going to see a drop in PH at different rates. You also have fish population and your water changes to factor in as well.



You'll never get all the waste cleared out of your substrate, no matter how hard you try. There will always be small amounts leftover. As this material continues to breakdown and decay, it will begin to form small amounts of carbonic and trace amounts of nitric acid in the water. This too goes after your PH and hardness. This is why you typically see mature tanks end up at a lower PH then they started.



Is this a desired result you are trying to achieve, or is this more about how to combat the corresponding drop that will occur? If you are trying to control it, I'd reccomend adding a crushed coral substrate or adding a hardness conditioner to the water you are changing out if that is a concern of yours.
