wish i had caught this thread before you bought the grapewood. grape wood is full of tannins and no matter how much you boil it or soak it, it will still leech out tannins and lower you PH. also, since it is not a hard wood, it is more prone to rot,mildew, and mold, making it less desirable for even a terrarium setup. if you want some cheap driftwood, check ebay, or check out the mopani wood in the reptile section of any pet store. mopani and manzanita are both hard wood and will do great. IME the grapewood isn't worth wasting your time with
