Activated Carbon Filter Media – 500g (10kg pack)
Activated carbon is an essential filter media for every aquarium and is ideal for both fresh water and marine setups.
As a chemical filtration medium, activated carbon effectively removes odors, detoxifies harmful metals, and purifies and softens water.
It works through absorption — pollutants are trapped within the porous structure of the carbon, acting like a molecular-level mechanical filter.
Activated carbon can reduce the effectiveness of medications used in aquariums by breaking them down. Therefore, it is recommended to remove carbon before treating the tank. Once treatment is complete, the carbon becomes highly effective at removing residual chemicals.

The carbon works well in my freshwater tank. I noticed a significant reduction in fish odor after a week. It’s easy to add and doesn’t clog the filter. I’ve used it for two months now and it still performs well.

Good quality filter media. I used it in a marine tank and saw a noticeable improvement in water clarity and smell. I removed it before treating for a parasite, which was a good move.

Very effective at removing odors. The 10kg pack is a great value for long-term use. I’ve been using it in my 100-liter tank for over a month and the water feels cleaner.

It works, but I noticed it didn’t remove a strong chemical smell after a medication. I think I should have removed it earlier. Still, it helps with general water quality.
