Fluval C3 Hang-on Filter for aquariums up to 190 liters. The large 5-stage filtration system creates a clean, clear, and healthy aquarium. It allows you to set the maximum surface area and optimal dwell time at all stages of the filtration process. Filter chambers include two mechanical, one chemical, and one biological. The mechanical cleaning cartridges effectively capture large debris. Activated carbon removes toxins. The Bio-Screen pad provides a friendly bacterial system. The C-Nodes technology features a patented refill control system that allows you to slow down water flow, creating a gentle current to protect delicate fish and plants. Slowing down water circulation extends the water filtration time, making the aquarium cleaner. The fully modular design lets you control each stage individually and change them at different times to maintain continuous biological activity in a stress-free environment. Designed to maintain the highest quality water, the Fluval C Power Filter offers comprehensive 5-stage filtration – two mechanical, one chemical, and two biological – for excellent results.
