When th filter was running it was very good. But one night it was very noisy and the impeller was not moving and 5 minutes later the motion sounded like it was going to blow up. For the three months it was the best filter. But in the long run it had killed my mated par of convict cichlids and two large male convict cichlids

AquaClear is the only hanging filter I ever buy for my tanks. They're simply the best.

Good filter that works well 11/28/2012
This filter works great. Just set it up, fill it with water and turn it on. It's runs quiet. Adjustable flow rate is a nice feature to the filter.
