Bubbles

[Jaws]

My live rock is covered in tiny bubbles. It's definitely not bubble algae however. Any reason why it might be doing this?

[Beverly]

How's your water flow over this rock? Is there red or green filmy or fuzzy stuff between the bubbles and the rock?

[Jaws]

No red or green film and most of the bubbles have vanished. I have a lot of flow in the tank but nothing that is creating bubbles. The bubbles did appear after feeding however. Could this have caused it by any chance?

[Beverly]

Your bubbles are a mystery to me. I can't see why feeding the tank would cause bubbles. That's never happened to me. Maybe someone else can shine a light on your bubble problem. How long has the tank been set up? What else is in it? Could microbubbles from your skimmer, if you have on, be causing this?

I get some bubbles on a rock just under my sump return. I am sure mine is caused by air from my skimmer getting sucked into my return pump and thus shot into the tank. The rock in question also has a light dusting of hair algae that likes to trap it. Every once in a while my Sea Hare will cruise by and trim it back, releasing the bubbles..
