Since upgrading from a 75gal RedSea 300xl to a Waterbox 230.6, the filter rolls for my Clarisea are only lasting me about 2week or so. I have the roller filter sitting as high as it'll go in the sump. I certainly have more fish in this tank than I did in my 75gal. Are others using this size roller filter with a larger aquarium? I'm wondering if I should upgrade it to an SK5000 model that has a wider roll? Most people I've seen here report that a filter roll last them a couple months, which is about what I was getting with it on my 75.
