need a little advice on buying a new filter box, both my filter box and uv has had there day the uv only works when it feels like it and the filter box had sprung leeks all over .So it time this week to replace both of them ,have heard that combind uv and filters are not that good allways have had separate uv and filter i noted that margaret said she likes the black box filter is that the one with just foam in it ,so any advice would be good as i really do have to get a move on to replace both of them and i would really like to try and buy what works best as u can be talked into buying allsorts at aquatic shops
