sand and bubbles

[dana307]

In my 30gal I have a mixture of sand, laterite and gravel. About 1" thick and higher in spots where I have planted pots which is towards the back. The other day I was poking around doing some water gardening and noticed that if I pushed my finger into the substrate I would release bubbles of air. Is this good? bad? okay? bacteria doing it's job?

sorry meant to post under freshwater general discussion and made a boo, boo.

I'd be willing to bet it is air that is still trapped in the substrate from when it was put in - especially if the substrate hasn't been given a vigorous stir. When I had sand in my 55g, it would release bubbles everytime I stirred it up, unless I gave it a good "swoosh" when I put it in.


That's just my guess, however.

yeh id agree with Leopardess i have a sand substrate for good 6 months and i still have bubbles popping up time to time.

Okay. Thanks for the feedback. Just thought it was weird and then recalled that I get these miscellaneous bubbles away from the bubble wands every once in a while. Got to wonder what the horse faced loach thinks of it when he is burrowing and gets blown back by an air bubble. Whoa!

yes, i though my plecos were farting when they stirred up the sand, before i saw all the bubbles trapped under the sand(i washed my sand too, so it was wet when i put it in he tank)....but that still doesnt explain where the bubbles come from when there on the side glass
