Great for small rimless tanks
This filter is on my 16 gallon cube and works perfectly as a filter.I have a low bio-load with just one fish and 3 mangroves so I don't anticipate any problems with filtration problems. I am very pleased with the look of the filter as well as the capacity for media. For my small aquarium this filter works very well. I'd be leary to use it on an aquarium that was much larger.
