Tunze DC 9410 not skimming

[Rshahnyc]

The pump seems on and I dialed it up. The water level is the same it was previously but now no bubbles.

I do have the air intake connected to a CO2 scrubber but this hasn't changed recently but the bubbles have stopped.

Any suggestions?

It worked previously? I would check the needlewheel and check the air inlet nipple on the pump for clogs and make sure the silencer hose is not kinked.

Is there a video on how to check these? Do regular tunze skimmer maintenance?

I'll take it apart based on this video and soak the parts and see if I cant free it up if there is debri

I do have a general video on this group of pumps and the maintenance. If the skimmer worked well before, it will either be an impeller issue or an air obstruction and the nipple on the pump does tend to clog with salt creep over time.
