Carbon Sans Filter Bags

[cav~firez22]

i use to use my fluval 404 for carbon only and i never used bags. aslong as the carbon is rinsed really well before going into the fluvy, there should be no problems. after 6mos i didnt see any carbon bits in the impeller or the tank. just make sure you use the top of the baskets.

the foam pads work well too.

I say your safe.. I never had an issue.
