my rock is getting 1-2mm bubbles forming on them. There are also bubbles on the glass whereever there is fine algae.Is this a problem as i rub them off and they form again in a day

I have a 600l tank been running 8 months. 50 kg live rock (coral) ans coral peices in the mini reef system. Good skimmer from Marco, replacing my Tunze as I felt that was too small. Bubbles are on green and red algae which is not long or too plentiful. The bubbles are shiny (almost silver). Can get a pic tomm
it could be a detritus buildup in the gravel if its crushed shells causing high nitrates and in turn your cyno and/or algae.direct air flow from my seio 820 removes the bubbles as does a fine brush.
tank is approx 600x600x1500 with a corner overflow.substrate is 50-60mm of fine shell. Have just added seaweed from clean water from Sheffield beach durbs
