bubbles

just out of curiosity, is it normal to have air bubbles throughout the sand bed? it looks a lot like swiss cheese with fine bubbles everywhere against the glass especially in the lower flow areas of my nano. i only have snails in there right now and they are doing ok.

Yup. Its normal. It sounds like CO2 is escaping ffrom your sandbed. Take a turkey baster is blow the bubbles off if ya want.

thanks guys. i'll probably leave it alone cause it looks kinda neat. i imagine the CO2 is from bacteria.

i've also noticed these tiny white specks that move like bugs on the glass especially where there is brown algae ( i guess cyanobacteria or diatoms). is this normal too?

Yep, those are copepods and amphipods.

It's not only normal, but is desirable. However, I thought that what we end up with after the denitrification process was nitrogen (inert, 80% of earth's atmosphere nitrogen?), not CO2.
