Polyfilter, Purigen, Neither, Or Other?

[MbunaJoe]

Large peacock and hap tank. Two FX6's and one FX4 with just mechanical and biological filtration in them. 125 gallon aquarium. Installing two Sicce Shark 800's and am contemplating adding Purigen or Polyfilter to the Sharks. The purpose is to improve water clarity. Looking forward to your opinions.

add alot of filter floss will help with clarity & also purigen will help also.

Read aquariumscience.org regarding filtration. Load your filters with 30 ppm poret foam. It absolutely works. You might also read what aquariumscience.org has to say about Purigen.
