I have a 90 gallon freshwater tank with 6 med-lrg goldfish in them. I have the fluval 404 as my filttration system and i have not been very happy with it. First of all goldfish crap like crazy and need a lot of filtration and it is a pain in the *** cleaning the fluval system. I'm thinking about switching to getting the emperor power filter 400 perhaps getting two of them. Do you guys think this would be a good idea?? anybody experienced any problems with the emperor power 400?? how quiet is it?? any advice much appreciated. thanks. bzboy :bowing: :bowing: :bowing: :bowing:
