Stuff in sand?

[Sean_Buckley]

A few days after I got my LR, at the front of the glass, I can see little holes in the sand. They seem to be in 1 area around the live rock, and although I've never seen anything moving around in the holes, I know that something made them. They're about a half an inch down in the sand, and are range from about .5 mm to 1.5 mm.

Pods or pockets of nitrogen gas. SH

If its pods, I know thats good. If its nitrogen gas, is that good or bad? What caused it, and if its bad, how can I get rid of it and prevent it. My sand bed is probably 1.5" or 2" deep in most areas, is that too deep?

Sometimes you can get a little bit of 'denitrification'. It's a good thing. SH

It's a good thing

As long as it's not too much, it gets released and nothing that burrows will run into it (wrasses etc)...

O ok, well, there's hardly any of them, so it'll be fine, probably. I'll just make sure it doesn't get too bad.

If your sand bed is operating correctly then you will find little pockets like this, its usually the sign of bristleworms, pods and gases. these are all good things and if your sand is shallow enough then there is no concern as things like fish and other creatures will turn the sand over and keep it fresh
