Tunze 9002 - still not skimming..

Yea mines been modified as well, it worked great til the motor crapped out, now I've just been losing hair over it. Lol

Well the only other thing I can think is that you may need to change the water line a bit to get the bubbles climbing to the necessary height. Then again I know sometimes my skimmer will go days without producing any skim mate even though most of the time it runs extremely efficient.

Are you running the 9002?

I've always found mine worked well at the specified height til now.
