The white material on the wood could be bacterial but more likely a fungus. I would take it out and pour hydrogen peroxide on it and scrub it clean,then put it back in the tank. If you have a big enough pot that you dont want to use for food you could boil it and then scrub it. This is not unusual for wood. If you didnt have the high NH3 I would suggest getting some Black Mollies to eat it up.
