!!!!!!!!!!! Driftwood Aquarium !!!!!!!!!!!!?

Ok so i have a large log in a bird cage with no birds in it any more and have broken off a piece (the wood is very old and extremely hard in the middle it is still red) and scrubbed it really hard and have put it in a bucket to soak and was wondering if this wood is going to work in an aquarium i am also going to boil it tomorrow for an hour then sock it again for about 2-3 weeks till i do my water change and have a red fin shark that im going to put in a small tank with the wood for at least 2 weeks. is this a good idea. do you have a better way of curing the wood ? plzzzzz reply
