ARL:
anaerobic means living only in oxygen rich environment, thats why the balls work so well with a slow drip, humid conditions but open to the air. they cant live under water so for you to say "They say that when more than 2 feet deep and slow drip rate even nitrates are broken down or controlled. How it does that is beyond me, cause there sure wouldn't be any enearobic bacterias present in that condition." ; would be just the opposite of what is a proven fact in every single professional aquarium world wide as they all use a similar form of anaerobic bacteria culturing just for the purpose of converting ammonia to nitrite - nitrate.
