cool i took the filters and pulled them apart and pulled the carbon out and swished the socks around in the small container of aquaruim water to rinse the carbon off and i did that with both saving the water then i took a brand new filter and put it over another small container and poured the water slowly over the new filter so all the water went thro the new filter to filter out huge pieces of carbon and what i was left with is two carbon free socks and a small container of this brown/black water that i poured into my tank as i thought this was all the benificial bacteria then i put the bio sponges in the carbon free socks and put them behind my carbon filter in pengiun so now the filtration set up in filter is biological , chemical, mechanical, biological(biowheel) i hope i did good
