I found some drift wood on the bank by my local river, but they were to big to boil. I rinsed then off and scubbed them, then I boiled water and put the wood in a covered trashcan to soak. I also used a cup of bleach in the water, and I have no ill side effects from this process. After I soaked the wood for 2 weeks, changing the water daily, I let it dry completely out. This was so that all the bleach would evaporate. After each of the pieces was completely dried I soaked the wood again in my brackish water using 4x the amount of declorinater. I now have the pieces in my 90 gallon brackish tank, and my fish couldn't be happier......
