i recently picked up a nice big piece of driftwood for my tank it comes bolted down to a slab of slate anyways the guy told me to let it soak in water for 6-7 days so the wood absorbs the water and it wont float to the top..and i've been letting it soak for almost 9 days now and it still floats like it did the first day i got it..has anyone had this problem or should i go back and ask for a refund cause personally i think he sold me reptile wood which floats i've never heard of soaking driftwood but then again ive had my tank for 4 months
