That's awesome!
Yeah, the sprouting leaves is because you didn't season it long enough. A few weeks isn't enough, you should let wood sit for a year to properly dry it out. Of course, you should take proper precautions to prevent spliting, like covering cut ends(end grain) with wax. This may slow the seasoning process a little, but keeps it from drying too fast from one point and causing spliting.
Once the wood has sat long enough, then, as others suggested, you should boil it to kill any nasties and help get rid of some of the tannins.
As you have found, you don't always need to fully dry your wood(or use dead wood), as long as the sap isn't poisonous to the fish. Does anyone know for a fact what(if any) sap is harmful to fish? I suspect pine, cedar and fur sap would be a problem, but I have never tried it to find out. From what I can tell it seems most hardwoods are ok. Anyone have any knowledge about this subject?
P.S. I just thought I'd add my thoughts here for anyone who finds this thread in the future. I think it's great that you updated it too. When doing research I often find threads like this that end with post #7, and I'm left wondering if it worked, or was a failure, and don't know if I should try it or not, lol.
P.P.S. Where's the fish?! The tank looks empty...
