I am thinking about buying a filter for my 140 and the filstar sounds good. my problem is that it doesn't come with media. I figure i will use eheim mechanical and biological media. When I bring the cost together to set up the filstar with the media that i would like it comes out to almost the same price as the eheim filter that comes with media. I understand that the filstar has a higher rate of flow but I am still rocking back and fourth. please help me with my picky decision.
