I’ve used this in my 50-liter tank for three months. Water clarity has improved noticeably, and I’ve had fewer water changes. The filter runs quietly and the medium stays effective even after several weeks.

Works well in a small tank. The bacteria colonization is visible after a few days. I didn’t need to clean the filter as often as before. Good value for the size.

After switching from a standard sponge filter, this medium helped stabilize my water parameters. Ammonia levels dropped quickly, and the tank feels more balanced now.
