Eheim 2026 Producing Microbubbles After Pad Change

[Geordie]

It's only about a month old, to seed it back when i first got it i was using some filterwool in the top chamber, I finally changed the top pad for the normal Eheim fine mesh, put it back together and now im getting micro bubbles, i can hear air inside when i tip it when i prime it i can almost get rid of them then they slowly come back

Ive tried taking the top pad out so there is alot of water between the first pad and the pump but it still gives microbubbles, I checked all the valves and put it back together there is no leaks.

This is driving me crazy, any ideas?

nm, looks like I have lost the pipe that goes between the pump and the first basket connection, unbelieveable
