today, a good friend of mine bought a new tank off ebay, which came with a interpet ipf duo 3 filter which he kindly donated to my good self so i gave it a good clean up and decided to read the instructions and noticed that it should have a filter media container to put carbon in but it was in use without so i would like to ask what what the carbon would be used for and if it will be needed for the filter to work properly? grateful for any advice - thanks.
