Fluval Biomax for all 3 baskets, u don't need that other crap.....IMO...
the FX5 is already a sponge king..the mechanical filtration is covered.
if i were u i would buy another filter to assist the FX5. i use a FX5 and Eheim 2028 pro 2 on my 120 gal. Eheims are great for biological filtration!
u wont regret buying one...
FYI those polishing pads are notorious for clogging and reducing flow. they must be bought again and replaced u cant clean them..
