GEO Reactor Bubbles

[LittleMaui]

Replaced the media in my reactor and seem to be having a lot of bubbles. I removed the media, checked for leaks and added some finer course media to slow the flow down, but still a lot of bubbles. Any ideas? Does it take a while for the media to saturate? I'm using Reborn media, carbon doser set at 4 seconds/bubble and the output is a slow drip.

Mine does that sometimes after the flow gets cut off. I think air gets trapped and recirculates. I tilt mine slightly, with a cloth under 1 side so I can bleed the air out thru the probe hole a few times.
