bubbles in sand bed ?
I have noticed air bubbles in and on top of my sand bed, particularly in one spot. I recently added a few sps coral to my tank and the bubbles are in the same area around the two corals. In this same area the sand on top is a purplish pink. My dkh is 12 my ph is 8.3, calcium is at 380 and salinity is 1.024. Can anyone explain this? Tank is roughly 3 mos old and I’m just as new to the hobby.

Sand bubbles can usually be three gasses. Nitrogen if you have a DSB and the bed is removing nitrate. Carbon dioxide, usually at night, produced by algae and oxygen, usually in the day, produced by algae or denitrification. A bubbly bed is an active bed and is, as Martha Stewart would say, a good thing.
