Micro bubbles

Not really that big of an emergency well for the past couple of days I've been noticing more and more nicro bubbles and its all in my display tank its very ugly have any ideas...

Here's what I have circulating the tanks 2 maxi jet 900 1 on each corner a penguin 650 for benid the rocks a cpr overflow box and a 500 gph return pump in a 40 gallon long

 

Where do they seem to be originating from? The sump return or the powerheads?

 

Sounds like you need to adjust the air or water flow on the skimmer in the sump.

 

That's the thing I don't see where its coming from they just appeared can't find the source

 

Shut the return pump off and see if they go away!

 

Ok will do at work right now and don't wanna tell girl friend to do it she might mess some thing up so gotta wait 12 hours.
