All I have are power filters. I am not confident enough to try a Sump/Wet Dry or anything specail, as much as I want to. For now thow, these filters work for me. I realy need to get onto of my game in the bio-filtration area thow. I have a very old "small" AC filter that I want to fill with Pot Scrubies. Will this work for a bioload of my fish. Can I just throw in some Pot Scrubies into all of my Power Filter? All I have are AC's with the bottom sponges right now. I need to impresse my Aquaculture teacher cause I want to be the best in class.
