Ok, in the October snow/ice storm of this year that hit the east coast an apple tree in our yard lost a few pretty big branches. My friend and I have planned to make some nice pieces of driftwood out of it. We plan to tie them up in the Deleware river to soak them and help get the bark off. Will that work good and be ok in a fish tank after some cleaning? They are pretty big- one over 5 feet long. Also is apple tree and crab apple tree wood ok to use?
