Air bubbles from powrheads?

[adamfinke]

Has anyone else seen this micro bubbles from a powerhead? Would a dirty powerhead cause this?
Thanks

I get my micro bubbles from the micron bag I use : ( ... Is the powerhead new?

The only time I get micro bubbles from my MP10's is when they are drawing in air from being too close to the water level.

^ this they create a crazy water cyclone if they are to close also.

+1. They cannot magically create air. They need to be dragging it down from somewhere, or they are chopping up bigger bubbles from somewhere else.
