### ⭐⭐⭐⭐⭐ Great filter
*by R***9 on July 22, 2025*

Great filter for my aquarium - works well at keeping the tank clean

### ⭐⭐⭐⭐⭐ A+
*by M***. on December 25, 2025*

Probably overkill, but I use these in a 2 gallon shrimp cull tank just to give me an edge over potential spikes in toxic substances. It also keeps the water crystal clear.
