REEF-SPEC Carbon 100g by Red Sea is an ideal additional filter media. It is suitable for both freshwater and marine aquariums.

A 100g bag will treat up to 400 litres of aquarium water for around 2 months. This time scale does depend on the waste load of the aquarium. If you are using it in a very dirty aquarium or if you are using it to remove medication it may become exhausted more quickly. However, because this carbon is so good, it will hold the toxins. Some cheaper carbons will leach toxins back out if you don’t remember to change them on time.

This carbon comes neatly pre-packed into a net bag for easy use. Simply give the carbon a quick wash and pop it into your filter or sump. It works best in an area of medium to high flow. To get an even better performance out of activated carbon, you can use it in a reactor. This means the carbon gets more contact time with your aquarium water.
