| Fluval 304 filter does not seem to work, please help Hi all, i got a new(used) tank yesterday and included with it was a fluval 304 filter, all was being used before i collected it, but i have put it back together and it does not seem to be wprking, the little fan in the lid is going round, all the media is in place etc and the pipes are connected; in the water the suction pipe is connected to the out pipe, and the u bend piece is connected to the in pipe, but there is no water going into the filter or coming out, i have tried putting water from the tank into the filter to force it through, but this hasnt worked either. please help as i have lots of fish that need their new home asap.
