If you're shopping for a versatile and affordable aquarium filter, MarineDepot.com's new GFO and Carbon Filter Media Reactors may be just the solution you're looking for. In today's video, we'll take a look at these economical reactors and show you how to install and run the single chamber model with carbon filter media.

Available in a single, double or triple cartridge designs for a variety of tank sizes, these brand-new reactors are perfect for GFO (granular ferrous oxide), activated carbon, biological and other popular aquarium filter media.

Marine Depot GFO and Carbon Filter Media Reactors come with everything you need to install except for the media itself and a water pump. That includes a filter wrench, quick disconnect fittings, a ball valve for precise flow adjustment and a wall bracket for installation inside/outside your aquarium stand or on a wall. The pump we recommend and used in this video demonstration is the Cobalt Aquatics MJ Multi-Purpose Powerhead/Pump. We used the 20-watt 295 GPH MJ1200 model which currently retails for $38.99.
