I was always told that a marine tank should not have bubbles. I have a reef and 3 powerheads. all three heads came with a clear tube and a little black thing that goes on top of it (venturi valve?) any way, when i put this on the heads blow bubbles. i have one head at the top of my tank with this on only because i have a tall tank with not that much surface area and the bubbles seem to get more movement than just the head alone.
should i keep this up? or is it dangerous to my reef inhabitants?
