My husband bought me a 29 gallon fish tank kit for Christmas. We rinsed the tank, the gravel, ornaments, and filter. We added the gravel, ornaments, water, filter, heater, and Neutral Regulator. After the tank was full of water we noticed little air bubbles everywhere on the tank. They're on the sides of the glass, on the gravel, and ornaments. Is there a reason for this? Also if you look up at the top of the water you can see little fibers floating (hair, dust, and particles from the gravel). How do we get rid of this? We turned the filter on as soon as the tank was full of water which has been running for about 4 or 5 hours.
