Boiling Rocks.

Waste of time. Just give 'em a clean and put them in. There are no parasites or pathogens on dry rock that you need worry about.

I think 45 minutes of boil time is extreme overkill, a 1 minute dip at 212 degrees is definetely enough to kill any bacteria found on the rocks. Same goes for driftwood, but you may want to boil them longer to take out the tannins.

if a rock is dry it will kill of any water-boure pathogens.

any other doubts can be settled by using bleach.
