thanks for replys, yes i checked everything and cleaned the filter and also where the impeller is seated, there is not blockage at all,i have pushed it down as far as it will go, it makes a small sound when you turn the power on, but nothing else, i took it out and checked it a few times , the bio-wheel does not have any sponge so at the moment i am floating it in the tank, just got my ammonia levels good, now this happens, there is nowhere to put the bio wheel in the small filter i am using, but i did put in the filter cartridge from the other filter so maybe that will be ok, should i used some Amquel plus incase of ammonia spike? I also cleaned the power filter with a specail brush so there is no gunk in it at all, it seemd to be better when it was dirty, now its clean it wont work at all
