JBJ U.S.A. Reaction Pro 2 Canister Filter

Maintain a pristine, crystal-clear aquatic environment with the JBJ U.S.A. Reaction Pro 2 Canister Filter. Engineered for both freshwater and marine aquariums, the Reaction Pro 2 combines multi-stage mechanical, chemical, and biological filtration with an integrated, high-output ultraviolet (UV) sterilizer to deliver elite-level water clarity and health.

Unlike standard filtration systems, the Reaction Pro 2 features an advanced, high-capacity media basket design that maximizes water-to-media contact, eliminating bypass and trapping fine debris with ease. The built-in UV sterilizer targets free-floating green algae, harmful bacteria, and pathogens at the source, providing an unparalleled defense against cloudiness and waterborne disease without chemical additives.

The sleek canister body is designed for effortless maintenance, featuring a quick-disconnect valve block that stops water flow instantly for mess-free servicing. Built-in conveniences like the integrated self-priming pump eliminate the hassle of manual siphoning, getting your system up and running with just a few quick presses. Whether you are running a heavily stocked freshwater community, a delicate planted aquascape, or a high-end marine reef, the Reaction Pro 2 series offers a professional, whisper-quiet filtration solution trusted by hobbyists who demand pure, healthy water.

What We Love About the JBJ Reaction Pro 2

• Integrated UV Sterilization: High-output ultraviolet sterilizer permanently eradicates green water algae and significantly reduces waterborne pathogens for ultimate disease prevention.

Key Features

Advanced UV Sterilization The built-in ultraviolet clarifier features an independent on/off switch, allowing you to run powerful sterilization to eliminate algae blooms and pathogens or turn it off when treating the tank or dosing beneficial bacteria.

Multi-Stage Customizable Media Trays Large-capacity media baskets come complete with foundational mechanical foams and biological media, while leaving ample space for you to customize your chemical filtration with carbon, resins, or phosphate removers.

Zero-Hassle Self-Priming Button Forget the old-school struggle of starting a siphon. The integrated ez-prime plunge handle rapidly clears air from the lines, instantly drawing aquarium water down into the canister to establish a fast start.

Whisper-Quiet Operational Performance Engineered with a dampening rubber base and a precision-polished impeller shaft, the Reaction Pro 2 delivers powerful, high-volume flow rates while keeping vibration and acoustic noise to an absolute minimum.

Heavy-Duty Quick-Disconnect Valves The robust, single-lever valve block isolates incoming and outgoing water lines simultaneously. This lets you carry the canister straight to the sink for maintenance without losing your hose prime.

Freshwater and Saltwater Compatible Perfect for heavily stocked freshwater community aquariums, African cichlid setups, high-tech planted aquascapes, marine fish-only systems, and coral reef display aquariums.
