I have a SWC 160 cone skimmer. I purchased it used from a member on here about 2 years ago. I have been using the mesh impeller that it came with but now there is nearly nothing left. The mesh is gone and most of the impellers are as well. I'm trying to find a replacment needle wheel and have searched quite a few threads on here but am really confused. People have new needle wheels other say new pump then others say that pump wont fit. What works please help. I have so few impellers left it barely looks like the skimmer is running so I need this fix fast.
