Nitrogen Bubbles in my Nano by the end of the day.

Well my tank has been up for 3 months now and doing great. Starting to buy the equipment for my 75 gallon. By the end of the day there are alot of nitrogen bubbles in my tank and on surface of the water. It really hasn't bothered me much. However, earlier this week the Xenia had two bubbles that were caught on its side. It now has what I can only call a scar where these bubbles were. Then the next day a couple more bubbles were right there. The Xenia looks health except that scar and the fact that the stalk with the scar on it is bent. Any thoughts?
