I have a NEXTREEF MR1 MEDIA REACTORS for $50 a piece. Both are in great condition. I purchased a media reactor with a built in external pump and no longer need these media reactors. They can be used for Saltwater and Freshwater systems and be used with Gfo, Biopellets or Carbon. Here is a brief description and a link for reference:
The MR1 family of Media/Substrate Reactors feature a massive 4-inch reaction chamber. The extra wide design maximizes water to media contact, increasing efficiency and minimizing dead zones in the reactor.
NextReef Reactors have the largest capacities around, giving you the ability to run large amounts of media, or multiple products simultaneously. They're ozone-safe, and perfect for phosphate control, de-nitrification or fluidized sand filtration.
The NextReef MR1 stands over 14 inches tall... that's over a half gallon, big enough for large reef systems - up to 250 gallons.
NextReef Reactor is hand-crafted in the USA from the highest quality materials, and CAD engineered/CNC cut for a precise fit.
