Air bubles on live rock

[choupic]

I have several small air bubbles on my rocks. I remove most of it by hand then they come back again. Could it be I have to much circulation. I have 2 seio 820 gph and one rio 200 gph (shooting surface).
And also battling cyarnbacteria (the red stuff).Its off the sand but now it's on some of my rock. If i take the rock out the water and scrub it off will it kill all the micro featherdusters on it.


Thanks
Lance

I'm super new to SW but some of my reading tells me this:

Deep in the rock the conditions are anerobic,meaning 02 free.Its in the anerobic pokets that nitrates get converted into nitrogen gas and will leave the tank as bubble.

The same thing can/will happen in a deep sand bed.

Its a good thing and I guess its the reason why so much live rock is suggested /gallon.

Please wait until someone who actually has a SW tank running to advise,but I think its ok.

Might be the cyano that's making those bubbles

Hey Lance , if you do take the rock out to scrub off make sure you wash it off with some SW and your dusters should be OK.

You want alot of good circulation if you have cyno
