Cant stop microbubbles

[Thomsona]

Hey guys and gals

The last week my rsm250 won't stop micro bubbling my tank up only way to stop it is turn the skimmer off
I've cleaned everything followed the trouble shooting guide watched the DVD and I still fix the mongrel

Any advice or tips tricks would be great

All live stock are happy except the shrimp there a bit spooked

I am thinking it is coming from the back chamber make sure it is full.

Tried everything in manual and with tech support can't get bubbles to stop

Are you running a HOB skimmer? If so turn it off and see if that is where they are coming from.

It's a red sea max 250 so it's all in built

Ok so micro bubbles have stopped but now I'm getting little to zero foam in the skimmer cup no matter how I adjust it

how long has the skimmer been running? there is a break in period u will go through. it will work it out soon enough just keep adjusting it till u get it just right
