You might be able to boil it for at least 10 min, this will kill any hitch hickers and help it to sink. There is a possibility that this will shorten the life of the wood, imho it is not signifacant compared to how long it will usually remain in a tank. You will need to scrub the peice after this. And there is always the fail safe, get some scrap slate tile, (the chiped or broken peices) from a big box store and some stainless steel screws.
