The drift wood is the cause of the problem. soak the drift wood in a big enough container for atleast a week. and that will slove it!
Not the case. Driftwood leaches tannins (an acid) and the OP's water is green as in an algae bloom.
AirborneAquatic UV will make all the difference in the world but do not rush out and get one. If your tank is not cycled you absolutly do not want to use a UV. UV will kill off the algae cells that are free floating in your water column (the reason it's green). It will also kill off any free floating bacteria in the water column including the bacteria you need to cycle your tank. Once it's cycled and the bacterial colony has established on surface areas in the filters etc.. you good to go running UV. If you truely have no nitrate readings you are not cycled. Algae blooms are very common when cycling a new tank. You have direct sunlight on your tank so lights off will not help much.
