air bubbles

[AndynSarah]

is it natural for a tank to develop air bubbles in the live rock? I am not adding any air to the tank just letting it run.

It is normal specially in new tanks under cycle.

If you're still having that algae problem, it produces Oxygen which forms the bubbles... So perhaps you're just having an algae problem on your LR...

Or nitrogen from the anerobic decomposition of nitrate deep inside the rock pores...
