Activated carbon is a chemical filtration media that is very well suited for removing dissolved organic compounds. The benefits of regular use are crystal clear water and removal of foul odours.
In normal conditions use 50g per 200L of water and place the carbon in a filter bag or reactor.
An increased volume can be used for medication or pollutant removal, in these cases double the volume can be used.
Replace the carbon every 1-2 months as it becomes depleted.
