Bubbles from sand bed
55G, argonite sugar fine sand bed, 1", cycled for 6 weeks. Now I see a lot of bubbles rise from here and there, a lot of them attached to the tank, and I also noticed tiny air pockets in the sand.
I did a google search and many mentioned that it is good thing and the bubble is probably Nitrogen. However, they all mentioned that "IF IT IS A DSB". Mine isn't a DSB, is it a good thing too? If it is normal, when will it go away? |

It may or may not be nitrogen. It probably is. If I'm not mistaken, it's probably a certain bacteria that is digesting nutrients and putting out gas.
I had something similar in my old tank, and it went away after a while. |

Could it be any poisenous gas? The fish (2 domino damsels) look fine.

If there was enough of them, potentially.
But the odds of it being toxic to levels that could actually damage anything is extremely low. |

its probably bc you put your sand in first then added water. the bubbles are just air.

Had the same thing happen when I set up my tank. Didn't hurt anything.

Could be the start of cynao, which I think puts out oxygen.

Not likely since the bubbles came out recently, and there is a spot that I added some sands later, the color is more white and there is no bubbles trapped in the sand. |

It's anywhere from an inch to 4 inches or more in places. Almost like mini sand dunes.

I doubt that it is nitrogen after only 6 weeks. Denitrification requires an established live sandbed, and depending on how coarse the sand is, more depth than 1".
My guess would be trapped air pockets slowly surfacing. Even though sand may have been added after water, it still does not eliminate this as a possibility. Microbubbles could be stuck to the sand grains going in, and they could just be regrouping. |

You could only be so lucky. ;-) get those damsels out of there

I have noticed Bubbles coming up from my sand it a few of my display tanks for quite some time. I know my sandbed is @ most 2" deep, but I do believe nitrification can occur as long as the sandbed is not distrubed (water motion, livestock, etc).
It is basically an anaerobic area in the sand that is achieving some level of nitrification. It's is completing the cycle of nitrite/nitrate and releasing as nitrogen into the atmosphere. IMO, you don't have anything to worry about fish or corals. Just keep noting any changes and test a couple times over a week to see if your NO3 is reducing over a period, that will either confirm or deny if it is in fact nitrogen.
