Review title: Broke after 1 week
Product review: This filter does not do very well with smaller substrates. My cascade filter died after about 1 week of use, and the motor was totally shot. The filter circulated the water well with a good flow rate, but this probably contributed to its substrate intake and demise. The filter would probably do a lot better in a tank with no substrate or larger sized substrates, but there are definitely sturdier choices available for internal filters.-TBM
