I currently have a 40 gallon saltwater tank. My primary filter is is a Whisper Power 60, with a Seaclone 100. My water quality is not doing so good for my 3 yellowtails, 1 domino, 1 yellow tang, and 1 piccaso. I want to upgrade to a Magnum 350 canister, dont know too much about filter. Can I remove the current filter and start the new filter without disturbing the biological filter? Or can anyone offer any ideas on how to upgrade to better filtration?
