Fluval FX5 Micro Bubbles

[Reefer140]

I have had a fluval running on my new 75 gallon for 7-10 days now and I cannot seem to figure out why its blowing micro bubbles...

Anyone have experience with these filters?

I have opened up the canister and rearranged the trays to make sure nothing is causing a blockage... Not the fix... Ive tried adjusting the flows.. Not the fix

What am I missing??

Any help is appreciated

Thanks!

could be a leak in the intake line sucking air in . if you shut it off and let it sit you might find it

I'm not familiar with the FX5 but does it have a pressure release to allow the air to escape. I had an old Eheim that had this option and helped tons.
