I have a new 220 comming next Monday and have a filtration question. I was going to use an FX5 but then I was thinking two 405's might be the better option cosidering I could alternate cleannings and could use one filled with bio media whlie useing the other for floss ect for filtering smaller particulates not to mention if somthing goes wrong with one I still have filtration. I also have an extra AC110 I could add. Any opinions or experiances are welcome. Thanks.
