I just broke the motor head on my Fluval 305 canister filter. I think I can super glue the piece of plastic I broke off back on... I was trying to pry the damn thing off so I can clean it, and the butter knife (I know, stupid) just snapped the motor head housing in one little piece, and it is right on the edge/seal. Does anybody think that if I super glued this plastic piece back on would work? If not, what should I do? I dont have enough money to buy a new filter, so I need some advice?
