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. The foam is easy to use and conveniently fits right in to the bottom chamber of the filter. The water flows right through and it seems pretty sturdy and not likely to fall apart.

This foam does a great job at grabbing and holding onto larger debris in the tank, like fish food or poop. It is easy to clean by just removing from the filter and washing out. Can be reused a few times without having to replace.
