Microbubbles from refugium

[ArchXIII]

So, yesterday I just added a fiji cube hob refugium to my tank (not running a sump, no room in my stand). And it's adding a ton of microbubbles. Is there anything I can do to stop it, or will it just run its course?

Literally waiting outside a store now, so I'll be picking one of those up to try it! Thank you.

Not that I can see. It looks like it's coming out of the pump that brings water in.

The connection tight. Is the pump housing lose or not on right

I checked that and it's all on tight as it can go.
