Hydra Aquatics BioPellet Reactor Product Details The Hydra Aquatics Biopellet Reactor is a great piece of equipment used to boost biological activity in an aquarium with the use of biopellet media. The reactor works by pushing a stream of water through an accelerator which agitates the media and puts it in motion within the reactor. This process is called fluidization. The efficiency of the media is increased it churns inside the reactor. The filtered water is then returned to your aquarium. One of the greatest advantages the Hydra Aquatics Biopellet Reactor has over its competitors lies in its innovative design. Hydra Aquatics has solved the two most common problems that plague standard media reactors by incorporating an inverted conical bottom and a top-fed flow accelerator. Most media reactors use a bottom-fed flow diffusion method through a plate. This smooth, constant flow is typically referred to as up-flow or reverse flow. Unfortunately, using this type of flow inside a media reactor usually causes lighter filter media to clump at the top and denser media to settle at the bottom. Using Hydra Aquatics inverted conical bottom and top-fed flow accelerator design, it is impossible for the media to clump together or settle completely at the bottom.
