Skimmer Problems

[discusdick]

I have a Coralife Supper Skimmer 220 (in Sump) that has quit putting bubbles out, much less microbubbles.
I have clean the venturi air-inlet but it seem to be not getting air into the intake of the pump. The impeller looks OK.
Any suggestions?

Have you tried disconnecting the air inlet silencer? It may be plugged up. Just unhook your tubing from the silencer and see if you get bubbles then.

I've tried running it with the air silencer off. No luck! Soaking part in vinegar now! Any more ideas?

Make sure that the tubing itself is clear and is not kinked anywhere. Also make sure that where the tubing goes into the pump is clear. I think that is probably the part that you are soaking in vinegar though. That's all I can think of right now.
