I have recently placed my order of a new Fluval U2. Although, I was wondering, does it require any sort of replacement? For example, I currently have a Stingray Filter which uses carbon/zeolite cartridge and some plastic foam in it. I used to have to replace the cartridge once a while. Does the Fluval U2 need this kind of replacing, providing that none gets damaged? Or do I need to replace the foam w/e once a while? If so, how long does it last ?
Thank you everyone!
