![]() 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..
