I have (or had, I should say) a Sedra 9000 running on my asm g4x skimmer in my classroom tank. Well, over the 2 week break the school was closed each time I tried going to add water to the sump (rubbermaid trash can) so the pump over heated and froze up the impeller in the shaft. Should I just chuck it? Or does anyone think it would be salvageable if I take the time to pry it out?
