Need filter media help right now I am running 1 hot magnum and 1 emperor 400, running pads and polyfill in the emperor 400 and blue sleve and charcoal in the hot magnum. I have another hot magnum on the side. What type of media should I use if I run 2 hot magnums and the emperor 400? Tank size is a 75 gallon got about 25 cichlids ranging from 2 inches - 4 inches.
