Yeah that's the airflow valve. I put that in and it done nothing until I pushed the water outlet halfway in and then had a few bubbles but not many.
I don't know if this will help

Hi guys and gals
I'm new here and new to fish keeping
I've just brought a 58l tank 60x30x33 and it came with an internal filter which is an eheim pick up 2008.
The question is, ive set it all up and turned it all on should the filter be creating bubbles or just a steady flow from it?
Many...
