Coral Essentials Activated Carbon 2L
Our Coral Essentials Activated Carbon is an ultra-high grade, bituminous carbon in a handy 2L bucket. It is a virgin activated carbon in pelletised form, typical size 4-5mm diameter and 6-7mm long. Derived from bituminous coal, its high activity and extreme surface area (due to the activation manufacturing process) make it ideal for marine aquarium filtration applications.
For aquaria, carbon can be sourced from animal bones, peat, coconut shells, wood, and bituminous or lignite coal. Bituminous coal carbon is widely regarded as superior, especially for filtration systems. Our Coral Essentials Activated Carbon is made purely from bituminous coal and is considered one of the best options for marine aquariums.

I’ve used this carbon in my 120-gallon marine tank for three months now. The water clarity has improved significantly, and there’s less organic waste buildup. The pellets are easy to handle and stay intact during filter cycling. No clogging issues so far.

Great product for removing tannins and odors. It fits perfectly in my sump filter. After a week of use, the water looks cleaner and the fish seem more active. I’ve not had any issues with pellet breakage.

Works well in my reef tank. The carbon lasts longer than other brands I’ve tried. I do need to replace it every 4-6 weeks depending on tank activity. Slightly more expensive than some alternatives, but worth it for performance.

Used in a new tank setup. The filtration performance is excellent. No noticeable coloration or odor after use. The 2L size is convenient for regular maintenance and easy to measure.
