I bought one of these a while back and loved it so much that I bought another one for my other aquarium which despritly needed cleaning it was very mucky and dirty and this Filter cleaned it right up along with me cleaning the rocks and stuff with a aquarium vaccum, but the filter did most of the work and the tank is crystal clear in just a week and a half. I was cleaning the filter daily and now every other 3 or more.
