SubRosa I do wear a size 9 1/2.
But sorry didn't leave much info. Tank is a 120 gal return is split into 2 return tubes with 4 nozzles going back into the tank. For some reason yesterday was making sounds after a water change. Then I turned it off and turned it back on. It stopped and saw plastic piece shot out. Lucky it was not the impeller. Pump is still working, but want to get a new pump just in-case. I feel that the 5000 is not enough flow on return maybe because of the 2 splits and 4 nozzle, flow might be cut down because of it. Tank is a freshwater planted tank, with Altums. Aqueon ProFlex Sump model 4 and the pump is sitting inside sump, maybe some
