I'm starting up a new tank, along with 2 other smaller tanks already running. Someone suggested polyfiber & I checked it out. Seems to do a good purpose so gonna try it. Question is, if I have HOB filters with carbon filled cartridges, do I replace the carbon filled cartridge with these or do I cut to size & squeeze it in there somewhere with everything else ?
