I'm also a proponent of boiling all DW before it goes into a tank. And ditto on the pouring, if it doesn't fit in a pot. Both help remove tannins (if you don't want those) and I feel it helps sterilize it a bit to reduce the change of introducing something harmful into your tank. But I'd also like to add that there is another, slower process for removing tannins, though it doesn't clean the DW. For this, you just soak it in water, and keep changing the water. And changing. And changing. Hot water is quickest, but whatever works. You can even put the wood in the tank of the toilet for a while (as long as you don't add chemicals to the toilet tank water), and the constant change of water every time the toilet is flushed with help leach your DW.
Three of my tanks are blackwater, so I don't try to leach the tannins out before adding the DW to the tank. But I am currently doing hot water soaks on a large piece of DW because its going into a clearwater tank. Its a process, but I'm trying to learn some patience. Good luck!
