I've just got a fx5 filter and I'm trying to work out which media I need and were to put it.
The filter came with pot scrubbers and bio balls, but I've heard there not the best for canister filters. So I was going to use something like fluval biomax media, but would I be able to use biomax in all 3 trays or should I use something else in some of them?
