Micro Bubbles

Does anyone know what causes micro bubbles. They seem to be comming from my sump return. I cleaned my screen on my Mag 7 and they are still spewing out of the return into the tank. You can barley see them comming out but they accumulate in the tank over time.

 

Is this new? you have an established tank....shouldn't be skimmer..if it's broke in already....

probably need more details specific to problem..possibly photos...
you might have an air leak in some of you tube..sucking in air along the way...wet.dry....possibly gettting aggitating bubbles from bio-balls area...(dont know anything about a CPR...) , being sucked up by the return pump...do you have a sponge between the bio-ball and pump area?

any addition of chemicals???

let us know, and we'll try to help!!

I would check your seals from the return line. It is possible there is a seal that is sucking air. Try useing electrical tape and sealing all your joints then one by one remove the tape. when the bubbles start you've found your leak.
