I was thinking about replacing my Fluval 105 with a brand new Fluval 106. The 105 filter has become quite noisey compared to when I bought it and it also the tubing connector has started to stick making it difficult to pull out for cleaning.
For biomedia I am using a mix of fluval ceramic rings, seachem matrix, and api bacti stars. The ceramic rings and seachem matrix have become heavily clogged with brown slime. Should I consider replacing them? The API bacti stars look as good as new and are very easy to clean. I was wondering if I should ditch the Seachem Maxtrix and Fluval Rings and opt for a few more API Stars? Is there really any difference?
