Currently its still producing microbubbles in a same way it was before - I can see they are going down from main chamber into the lower and to output...

Checked ozone input and its closed for sure.

Will do video tomorrow and post here...

Hope its just breaking in again and bubbles will stop...

Thanks a lot and will keep you posted!

If you just started the skimmer for the first time after pulling it out of storage, it will take a week or so to break in again after drying out during which time microbubbles can be expected.
