Best Media for a heavy Bio load.
I just got a FX6 YEAH. And Need some advice on what is the best thing to fill my Filter up with. ( it has compartment in it )
I know one compartment will have by Bio-rings. They have some already in there , however since I want to keep some of my good germs I am going to put some rings from my old filter in there.
So what else should I add. I normally use ammo stuff from National Geographic, and Carbon.
Is that a good set up or should I use something else to get the best BANG for my buck. I was thinking of using something called K1.
