so about a week ago after doing a water change i found my fx6 stopped working. i thought nothing of it and thought maybe it was just self priming itself. this week when i was doing a water change i found that it still wasnt working. when i opened up my fx6 the water smelled foul and it stunk up my entire house. i opened it up to find that the impeller is cracked. i called fluval and they are going to send me a new impellor. but it will take a week. seeing that the filter media inside the fx6 is already dead, should i jsut start it all over? or should i just clean it of and try to put it into one of my sumps. i am afraid the dead bacteria will affect my filtration.
