On the surface of my tank I have one inch by one inch circle of bubbles floating in the centre of the tank and they are not dispersing. Last night I broke them apart and thought they were gone but hey they are back this evening. My water is crystal clear and I did a 15% water change over the weekend (I do them every weekend). Should I be worried about this or is it nothing?
