Bubbles coming from my sand

[dralarms]

I have been watching my tank, more today than usual and noticed bubbles coming from the sand. Should I be worried? What can be causing this? TIA

It is just gases from the bacteria in your sand converting waste. It is good.

If you have a SB then its just gas being released from the lower levels.... It's just part of the denitrification process.... this is just my uneducated guess
If you don't have a SB then I have no clue.

Even without a dsb this will happen. I don't have a dsb and I get some bubbles. It is your sandbed converting(NO2 to NO3)

 

[seaham358]

Actually it turns NO3 into nitrogen gas... This reduces that NO3 in your tank.

OK so it's good? That's great.

How deep is your sand bed? Just curious...

The two main gases produced by denitrification are nitrogen and CO2 in a shallow bed. Both are a good sign and nothing to be concerned about.

I guess about 2 1/2 inches, never measured it and was going to add some more sand but never got around to it.

Maybe your goby farted.

Don't have a goby, do have a scooter blenny but he was on the other side of the tank.

I'm laughing...

I get the bubbles when my hermits or scooter walk across the sand bed. I guess I never gave it any thought.
