I used this insert after setting up a new tank and noticed a significant drop in ammonia levels within a week. The filter fits perfectly and the water clarity improved quickly. Great for new aquariums.

It worked well during a spike in ammonia. The insert is easy to install and stays in place without shifting. I plan to use it again when I add more fish.
