I think it's a great idea and helpful if the suction was better. I need to reattach it again to the tank two or three times a week unfortunately.It took some time for my fish to get comfortable with it, but it only took a day or so. Works great to keep food from being sucked up by the filter when suction does work. The fish don't seem to care about the jellyfish, so I don't use it.
