OK I'm running this Fluval on a 55 gallon, using the pads, carbon, and biomax. Bottom 2 baskets are carbon, top 2 biomax. Anyway it seems like some particles are making it out of the filter, is there something I can put in the baskets that's finer - do people use floss in there or something like that? Just looking for suggestions. Tank has been up & running for almost 3 months.
