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.
