Blue Marine Multi Reactor 2100 is designed for demanding and large aquarium systems requiring powerful and adjustable filtration. The reactor allows the use of large volumes of filter media to precisely control water quality, including activated carbon, phosphate and nitrate removers, resins and biological filter media.

With an internal capacity of approximately 3.5 litres, the reactor is ideal for systems with high bioloads where stable and continuous filtration is essential. The included fine foam makes it suitable even for very fine media, preventing channeling or media escape. Its wide cylindrical design ensures uniform water flow through the entire media bed.

The Multi Reactor 2100 can be connected to a dedicated pump or integrated into an existing filtration circuit. The removable lid allows quick and easy maintenance, making it a practical solution for large‑scale aquarium installations.
