Micro bubles in return.

[GeoHawk]

About every 15 minutes or so I get a burst of microbubbles coming into my display from my return. Anyone know how to fix this. It is not constant just a quick burst.

Is there anywhere in the return air could be building up?

I have a valve on it so maybe there. There is also pvc where I connected the hose.

if there is any threaded connections make sure you use teflon paste to seal the threads.... if it's a new system it will prolly go away after a slime coat builds in the plumbing... it's not un-common for a new tank with new plumbing to have bubbles here and there... needs to break in just like a skimmer... also make sure your return pump is not causing a vortex "mini tornado" and sucking in air every once in awhile...if it is try a 45* elbow on the intake to stop it....

Fixed it! The return was causing vortex every once in a while in front of a koralia which was spraying bubbles everywhere. So I adjusted the return and its gone. Thanks!
