I have a 100 gallon tank with carbon balls, 2 NS70 pumps (top and bottom return), protein skimmer, and a top off tank. The tank is 90 days old. I have had problems but the tank is now stable. Cycled well and the nitrates, PH and salt are great. My problem is that the water is crystal clear but I have what appears to be small cotton fibers floating through out the tank. My lps says it is air bubbles but I think not… What is it? How can I clean it off? Please advise!! :help:
