Air bubbles on rocks and algea prob. Hello I have an algea problem sorta and im not sure why. I have tested my water with nitrits 0 ammonia 0 nitrates close to 0 and phosphate 0. I have noticed that there are a lot of air bubbles on my rocks either on the algea or close to it. Could this be a problem or not. The algea is kind of a brownish and green color and its on some of my rock and on my glass. Any suggestions would be helpful. |
