thanks for the reply Trey. I am using cycle, but that is all. and as for fish 2 damsels and a hermit crab. I really think it was your first suggestion, it might be the bacteria form the sand dying off, because it only seems to be on the new sand bed. I am going to get 2 power heads tonight or tomorrow morning. I will keep you posted
Thanks alot

Diatom algae, which are common in a cycling tanks, will produce oxygen bubbles in the process of photosynthesis.
