The Aquael Gravel & Glass Cleaner simplifies the regular cleaning of any aquarium. Without initial suction, the waterflow is simply started by shaking the Gravel & Glass Cleaner vertically. While the water is being pumped out, the specially shaped mulm bell can not only be used to loosen and clean the substrate: it also makes it possible to clean the glass panels thanks to an edge shaped as a scraper. In this way, any aquarium can be cleaned quickly and thoroughly with only one tool.
