Fluval AC20 Power Filter System

Give your aquatic pets a cleaner, healthier home with the Fluval AC20 Power Filter System. This filter provides advanced multi-stage filtration in a compact design made for aquariums up to 20 gallons. Backed by over 40 years of trusted performance, the AC Series is known for its reliable operation, quiet performance, and user-friendly maintenance. The AC20 uses 4-stage filtration - two mechanical layers plus chemical and biological media - to deliver clean, clear, and balanced water conditions. CycleGuard™ technology allows each media type to be replaced independently, ensuring your aquarium’s nitrogen cycle remains stable and your fish stay healthy.

This filter also features Fluval’s patented refiltration system, which extends media contact time for improved efficiency and water stability. An adjustable flow control lets you customize circulation, while a pre-filter strainer prevents debris from reaching the pump for consistent flow. The redesigned media basket offers easy access for faster maintenance, and the rotor system has been engineered for smoother, quieter operation. Made in Italy and suitable for both freshwater and saltwater environments, the AC20 comes ready to use with Bio-Foam, BIOMAX, and Activated Carbon included. Experience superior clarity and healthier aquatic life with the Fluval AC20 Power Filter.
