에하임 액티브 활성탄

The granules are really clean and dust-free compared to other carbons I've tried, so my water stays crystal clear right from the start. It pulled out a lingering fishy smell from my tank in just two days.

The water stayed crystal clear even after I overdosed medication for ich, and the carbon pulled the smell out within a day. It's a bit pricey for the bag, but I only had to replace it every few weeks with my bioload.

My tank cleared up noticeably within a few hours of dropping this carbon in, and the water has stayed crystal clear for over a week now. It's definitely doing a solid job pulling out odors and any leftover medication.
