so my 330 is finally up and goin. i want to get a big branch piece of driftwood to put in it. the tanks footprint is 6x3 feet. now i dont have 200 bucks to spent on a piece of wood and was wondering if i can just go out and find a piece i like. is there a certain type of wood i need to look for and what do i need to do to make it able to be in the tank? i live in central florida thanks
