There are just tons of places where we can find wood but I like to increase the odds on things. We can go around hoping but I find it works much better if I look for ways to change up the odds so that my chances are better. Sometimes it is as simple as being on the correct side of a lake or river. Notice the far bank of this little cove? If you walk up to this little spot but you are on the wrong side, you may see lots of wood but not be able to reach it or bring it back. That's where the magic of aerial photos can be a big help. Just getting on the correct side can make a major difference.
For treating wood, I handle the process in much the same way. I look for ways to increases the odds of getting a good result. There are lots of ways to treat wood but I want the one that gives the best result with the least time, effort, and expense. An overnight bleach soak works best for me. I can put it in any container that fits. Even the tank if it is a new setup, add a 1/2 cup or so of cheap bleach and go on with other things until I get back to the project. When I get back to it, I rinse the wood and lay it out to dry. When it is dry and all the smell of chlorine is gone, I know the odds are very good that I have a safe item. Bleach does the complete job of cleaning which many other methods miss. Pouring hot water doesn't reach the interior cracks where eggs might be hiding. Boiling doesn't remove oily residue but just moves it around to other spots.
When I pick up wood, I have no idea where it has been. Some meth cooker may have just dumped his leftovers there last week!
Bleach may turn the wood white but it returns to normal once it is in the water for a week or so.
We all take chances and hope things work out but I like to tilt the odds in my favor!
