its not just the media that bugs me the most, its the quality of the product and how easy it is to use
i have a range of filter that i run fluval - 204,304, 404, fx5s and the eheim pro 2 2028 is the best one
like i said before the fx5 is the most valve for money selling from $450-$700 (excluding media) when the eheim pro 3 2080 is about $1140 but includes eheim media
