Answer
Hello Ella,

     Please give me some more info on what type of pump and filter system you are using. Have you had your water analyzed by your pet store? Are you using tap water? If so, bring them a sample of that, too. What type of fish, and how many, do you have? Do you have any live rock or live sand in the tank? You should not have bubbles on the surface of the water or little white particles either. Your protein skimmer if set too high 1. will overproduce many fine bubbles and 2. waste collected on the skimmer walls may exit as fine particles into your tank. Please get back to me with some answers and I will try to help you, further. Thanks, Gerry.
