Filter Upgrade

Product is easy to install and fits the standard Hagen filter. The original filters I purchased approx. 5 years ago, only had the foam and carbon media. This product maximizes the effectiveness of the filter system. I have two 110 filters in a 75 gallon reef aquarium and haven't had any problems with the filters. They are simple to use, durable and easy to clean.
