With their many years of experience, Juwel have produced effective and easy-to-use filter systems that blend in with almost any aquarium. The internal filters are equipped with various filter media in a modular system. This means that a Juwel filter can not only be individually equipped, but is also easy to clean. All elements of these filters can generally be easily removed and cleaned. Whether it's the small BioFlow ONE for up to 80 litres, the beginner BioFlow Super, which can clean an aquarium with a volume of up to 150 litres, or the Bioflow M, L, XL for up to 500 litres of aquarium size, Juwel has a suitable solution for every tank.
