I have only had my tank for about 2 weeks, and I am a novice fish owner. Can anyone tell me what this is and if it is harmful to my fish? If so, what can I do to get rid of it an dprevent it from happening again?
do you have a air stone in the tank? if so, it sounds like micro bubbles.
i have the same thing, i get micro bubbles everywhere and it makes the water look cloudy.
In my case it was just air bubbles also. I got nervous at first but thats all it was. Take a real close look at it and see. If your still not sure take out a scoop of it with a cup and see if the bubbles disappear, then you will know.
