JNS Fluidized Media Reactors

JNS Fluidized Media Reactors are multi-purpose aquarium water filters specially designed for use in marine and reef aquaria. Insert your media of choice to help eliminate organic pollutants, odors, discolorations, and algae fuels.

Fluidized reactors, also commonly referred to as phosphate or media reactors are one of the easiest and most effective ways to use filter media in a saltwater aquarium system. These versatile filters are capable of running several different types of filter media, from activated carbon and granular ferrous oxide to resin and nitrate-reducing media.

The up-flow design of JNS Fluidized Media Reactors helps to keep filter media suspended and evenly dispersed to provide maximum contact time between your aquarium water and the media inside the reactor. Water is introduced into the bottom of the filter and then gravity pushes it upward through the media and backs out into your tank.

JNS Fluidized Media Reactors are computer designed, precision-cut, and made of polished A-class acrylic. All JNS media reactors are rigorously tested in saltwater environments to ensure reliability, efficiency, and affordability.

JNS Fluidized Media Reactors require a small pump/powerhead and tubing (sold separately) to push water through the reactor. You can plumb the reactor using 1/2″ flexible vinyl tubing. Using a ball valve is highly recommended because it will allow you to regulate the flow rate. Since different types of media have different flow rate requirements, be sure to reference the manufacturer’s suggested flow rate for the media you intend to use (it’s usually listed in the product description and/or on the product label).

An optional hang-on adaptor (sold separately) is available for additional mounting configurations.
