Review on Fluval Hagen 407 BIOFOAM MAX by Eufemia Ragi

I bought this product based on the reviews and wanted to try a different filter as my aquarium was not getting as clean. After 20 days with these filters my tank is dirtier than before, cloudy and 3 of my fish have died. I took out the filters, there was almost no dirt on them. That meant they weren't doing their job, which explains why my tank was so dirty. I do not recommend this product to anyone and will return to the Fluval biofoam filter.
