Micro Bubble everywhere

So I Fired up my 40G with a DIY overflow and closed loop. The Closed loop is spewing Micro bubble like mad. I turn off the CL and the bubble were gone.
Now how can I determine were the air is coming from
The input is PVC Pipe running from the bottom of the tank over the side and then converted to Flex and into a MAG 5. The output of the MAG 5 is flex to a SCWD and the outputs of the SCWD are flex then PVC and hard plumbed to bulkheads in the side of the tank.
I have no water leaks even with power off. and the bubbles are coming out of both returns.
So I would assume the air is getting in before the SCWD.
Is there a simple test to find air leaks

Thanks
Jason

You can tape off all the joints and remove them one by one. I found a leak this way.

I had a simliar problem, I was able to listen for the bubbles in the PCV, trace it back then reseal the joint. Pain in the but....

I FOUND IT!!!

Using Deb's and Snoop's Methods combined. It was the barb fitting on the intake line.

Thanks so much
