Great for keeping fresh water tank clean

I use this on my freshwater tropical tank and it helps keep it clean. It reduces toxins in the water. When you first use it a dark haze may come from the filter

I use this on my freshwater tropical tank and it helps keep it clean. It reduces toxins in the water. When you first use it a dark haze may come from the filter. This is very temporary and will clear out great and quickly. I recommend washing the filter media first before putting it in the filter to minimize this. With it coming in it's own bag it is very convenient and easy to replace in the filter.

I'm using this in a Fluval AC 20 on a 20 gallon long tank that I am setting up for my Sakura orange cherry shrimp. This is easy to use and conveniently fits right in to the chamber of the filter. The water flows right through and it seems like it will improve the water chemistry.
