I am going to be using a fluval 404 as the biofilter on my 150 and was wondering if I should fill all of the baskets with the ceramic bio noodle thingys (I think thats the technical term) or should I use some carbon? I am going to use two AC 500 for mechanical and I think I will use one & half foam blocks, should I put carbon in there? I think I will also add either one large or two medium powerheads with quick filters. Thanks!
