Aquarium Advice Activist
I have an aquaclear 50 and it seems to let out a stream of airbubbles evey minite or so. Is this normal? Should i take it back and exchange it?
What you are experiencing is likely cavitation, when you pull too much water through a restricted area, it releases oxygen.
This is not a bad thing especially if it's only intermitent. Pull the intake off and inspect it for debris. I'm sure that will fix your problem!
Good Luck,
Jason
