The vertical air intakes on the corners should be much more effective at trapping dirt at the bottom of the hospital tank. I was a little concerned after reading reviews from other buyers about the fragility of this filter but found that it will be fine as long as it is not hand handled (e.g. by pressing it into gravel) , but treated gently. hold over the base to limit the buoyancy of the filters and I'll definitely try! Nice little filter for a small footprint!
