Experience Level: Intermediate

Poor noise levels

The Marineland Penguin Bio-Wheel HOB Filter line is successful at keeping consistently clear water; however, after having one on my tank for only six months, it has begun to have impeller issues that make it impossible to keep the filter running if you are even two rooms over. the impeller and metal shaft are of poor quality and make a horrible sound like that of an engine underwater. Also, the exit site of the water has a lip on it that causes the water to make an unbearably loud waterfall sound that is anything but relaxing. I will not be buying this again.
