Fluval AquaClear 70 Power Filter The Fluval AquaClear 70 Power Filter is a powerful hang-on-back aquarium filter for freshwater and saltwater aquariums from 40 to 70 US gallons / 152 to 265 L. With 300 US GPH / 1136 LPH maximum flow, a larger filter body, 4-stage media layout, and adjustable refiltration, it is built for aquariums that need strong clip-on filtration without stepping up to a canister filter. AC70 Power Filter for Larger Displays The AC70 gives larger aquariums more water movement and greater media capacity while keeping the clean, serviceable AquaClear hang-on-back design. It is well suited to larger community tanks, active freshwater fish, planted aquariums with higher debris loads, lightly stocked marine systems, and aquariums where a canister filter is not practical or preferred. AquaClear 70 High-Capacity Features 4-stage water cleaning: Combines pre-filter mechanical capture, Bio-Foam, activated carbon, and BIOMAX for comprehensive aquarium filtration. CycleGuard biological protection: Independent media replacement helps preserve beneficial bacteria and reduce disruption to the nitrogen cycle. Patented refiltration system: When flow is reduced, water can be processed through the media chamber multiple times for better contact and clearer water. 300 US GPH maximum flow: Provides strong circulation and debris movement for aquariums up to 70 US gallons. Adjustable flow control: Output can be tuned for fish behaviour, plant movement, feeding, or reduced turbulence when needed. Pre-filter intake sponge: Helps prevent larger debris and algae strands from reaching the pump, supporting steadier long-term flow. Quick service media basket: The reconfigured basket organizes each cleaning stage and simplifies routine filter maintenance. Updated quiet-operation design: Rotor and cover improvements help reduce vibration and sound in the aquarium area.
