  • Actual colours may vary. This is due to the fact that every computer monitor, laptop, tablet and phone screen has a different capability to display colours and that everyone sees these colours differently. We try to edit our photos to show all of our products as life-like as possible, but please understand the actual colour may vary from your monitor.

Activated carbon absorbs dissolved contaminants such as chloramine and chlorine, tannins (which colour fish tank water), and phenols (which can cause odours).

Marltons Activated Bone Charcoal will enable fresher, cleaner aquarium water and can ensure that your fish tank water doesn’t turn yellow. Activated carbon has been used in home aquariums for decades.

Carbon is exhausted relatively quickly when used in an aquarium filter. For this reason, if you use activated carbon continuously, the carbon should be replaced regularly.

Activated carbon is made from carbonaceous material. It is heat-treated at very high temperatures to create many tiny pores, greatly increasing the surface area. These tiny pores and massive surface area allow the filter media to trap a large volume of material, thus making it ideal for removing pollutants and contaminants from air and water.

Marltons Activated Bone Charcoal is best used in conjunction with Marlton’s Filter Floss (padding designed to catch more considerable waste and debris in your tank).

Marltons Activated Bone Charcoal is available in a 250 g bottle.

Directions for use

Since activated carbon binds with the pollutants it removes, it will become saturated and can no longer remove additional pollutants. Therefore, the carbon must be regularly replaced—once per month is usually sufficient. Longer times between replacements will not harm your aquarium, but the carbon will gradually lose its ability to remove toxins and pollutants from the water.

If your aquarium water turns yellow or you smell an odour, it is time to replace the activated carbon in your aquarium.
