(nitrogen?)Bubbles coming from substrate

[dakota9]

On top of my recent lighting problems, combined with a powerhead that was releasing voltage into the tank, I've noticed these small (not micro-small as in turbulance) bubbles coming from my substrate which b-line verticlly through the water colume.
I think I remember that it could be nitrogen but uncertain, and think it's benefical, but again, uncertain.......

Any thoughts?

Do you have a deep sand bed?

 

[dakota9]

Yes and no...... It's deep, about 3", but its made of shells, tiny bi-valve mullosk shells. All the rage 20 years ago, kinda cool, but not used much anymore because of nitrite scare, of which I've not had a problem.....

Does it smell?

 

[dakota9]

Not that I can tell........

....... Wait a minute, was that a trick to get me to walk to my tank and bend down and sniff it?

Because that is what i did

LOL. I think he wanted you to see if the gas was sulfur based. It would smell of rotten eggs. It's probably nitrogen gas though, its a good thing.

Most likely they are just accumulated microbubbles being released.

Its absolutely normal.

Have you increased your lighting period.

Don't worry as I said its normal.

Once again, I think Simon nailed it, as my tank was dark for almost 2 weeks when I upgraded to the metal halide, I've been uping the photo period a little everyday to acclimate my soft corals to the stronger light of the metal halide

Thank you guys!
