    It could be oxygen bubbles that are produced from algae on the rocks. A pic would help a lot but if it is clear bubbled then my guess is oxygen bubbles.

    I agree with Marius, you could have some algae on the way.

    Lower your nutrients, get some clean up crew if you dont have. You would have to find the source of the nutrients. If it is only on selected patches of rockwork then it could be phosphate leaching out from the rock. Some phosphate remover in a reactor will help with this.
