Help, micro bubbles?

[metalmulisha]

I just repaired my sump from a small leak that started seap through the stand. There are no more leaks due to 3 days passing (knock on wood). But I noticed my FREAKIN bulkhead that connects the sump to my external pump and into the tank has a small drip. Plus I'm getting micro bubbles. Could this little leak be the cause of the fine bubbles. The very very very slow drip is coming from the bulk head and down the sump.

So far there is no leaks on the output of the pump and into the tank.

As far as input from the sump thats the only leak?

Can anyone verify if this little leak could be the culprit? Thanks

If the leak is in a return line it can cause bubbles. However pinhole leaks in plumbing aren't the culprit as often as people like to believe but they can cause micro bubbles.
