I bought one of the pieces from petsmart that was already submerged in water and had a java fern attached so there was no boiling. I didn't want to lose the plant. Another piece came from my LFS
and was submerged already so I didn't bother boiling it. The biggest piece I have came from the same LFS
but wasn't submerged. I'm not sure what kind of wood it is. I attached a java fern to it after it was in my tank a couple days. I think that's the main one that's causing most of the problems. I wouldn't mind detaching the java fern to boil, but I don't have a pot big enough to boil it in. Any ideas what else I can do?
