So I've been running with carbon and peat granules in the first two compartments of my Fx5 and Biomax in the last. I want to refresh my media and make it more efficient. I've been reading that carbon is basically useless unless you are treating for chemicals.
What type of filter media do you use?
What do you suggest I fill my Fx5 with?
