The ceramic media works well in my nano tank. I noticed a steady drop in ammonia levels after setting it up. I follow the weekly water change routine and use Reptisafe when refilling. The filter runs smoothly and the water stays clear.

I’ve used this media for about three months now. It helps maintain stable water conditions. The filter is compact and fits well in my small tank. I still do weekly water changes as recommended.

Great product for a small tank. The bacteria colonization is visible after a few weeks. I didn’t have to adjust my water parameters much. It’s simple to install and effective.
