I have an IN-250 Rev A skimmer and had the impeller problem that many people had. I got a new impeller from PA and the unit worked great for a couple of months.
This morning, I heard a strange noise from my tank. Kind of a grinding or vibrating sound. I isolated it to the skimmer pump.
So I pulled it out and thoroughly cleaned it with a vinegar solution. Put it all back together and still have the noise. It still pumps and the skimmer is working, but it is very loud and I am concerned that it will fail.
Any ideas? I have already contacted PA, no answer yet.
Thanks, John
