I found a good deal on some manzanita driftwood. I have a option of natural and sandblasted. I believe the natural still has bark on it. i would assume I want the sandblasted but wanted to check to see what everyone's opinion is. Info on tank, 8ft 240 gallon, tank inhabitants are 3 motoro rays and several geophagus. Sump filtration with tons of lava rock and marine block. Thanks in advance.
