Just purchased a FX6 (Petsmart had an unbelievable deal for $275) and I am wanting to setup this filter correctly, so that the fine mechanical media is placed BEFORE my bio so that the pores in the bio dont clog up with crap (As per PondGuru). Considering this, do I place the fine mech on the top tray or bottom? I dont use chemical media so the center is just gonna be fine mech + bio.
Thanks Friends
