Shut down my return pump and skimmer to do a water change. Thought it was working ok prior to turning it off, didn't look all that closely though. Anyway, plug it back in and it just slowly fills the skimmer part way back up, very few bubbles generated. It's a Sedra 3500 pump. Have never had to troubleshoot one of these things....what should I do first, second, etc? thanks
Oh, and it doesn't appear to be all that dirty.
