AquaMaxx 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 AquaMaxx 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 back out into your tank.
AquaMaxx Fluidized Media Reactors are available in two sizes: Standard and XL. They are computer designed, precision-cut and made of polished A-class acrylic. All AquaMaxx media reactors are rigorously tested in saltwater environments to ensure reliability, efficiency and affordability.
AquaMaxx Fluidized Media Reactors require a small pump/powerhead and tubing (sold separately) to push water through the reactor. You can plumb the reactor using 3/4" 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).
All AquaMaxx products carry a 90-day manufacturer warranty and include detailed instructions and diagrams to help hobbyists get up and running immediately.
AquaMaxx AquaMaxx is a Southern California-based aquarium supply company that entered the market in mid-2008 with a line of affordable metal halide bulbs. The brand quickly gained recognition as word spread about the high quality and low cost of their lamps. In 2009, AquaMaxx released a line of aquarium filter socks and, in early 2010, unveiled an assortment of high-performance protein skimmer accessories and upgrades.

I was looking for a Reactor to fit my 300 gallon reef tank and it was very hard to find something that I can put all the GFO that I need. that I can put a small pump to move the media so easily nice way I can fill it the reactor is completely awesome I love it. 😘
PROS
Huge Capacity, Awesone Versitility and Quality
CONS
One would need a good overhead space for an in-cabinet installation and maintenance
REVIEW
Awesome construction and design, affordable and nice functionality. It’s huge, this one is able to handle as much as 500gal with the media it can accommodate (GFO), and 300gal for Activated Carbon Filter media. I originally purchased this with the intention of converting it to an algae reactor. Ho...Read More
Awesome construction and design, affordable and nice functionality. It’s huge, this one is able to handle as much as 500gal with the media it can accommodate (GFO), and 300gal for Activated Carbon Filter media. I originally purchased this with the intention of converting it to an algae reactor. However, I had to run it with the GFO filter media I bought with it (Aquamaxx HC GFO). I guess having these functions: Carbon/GFO reactor and could be an Algae reactor with the addition of an led light strip or a solid grow light, I’d say it’s a money saver for its versatility and affordability without disregarding quality. It’s a great buy!Hide
This is my fourth I purchased. Using this one again to fill with Seachem DeNitrate and used on another freshwater tank. Just the right product for my application. I use other Aquamaxx products as well (protein skimmer & Bio reactor).
I use many Aquamaxx items and this is the second XL I purchased. I have the first on my 180 Cichlid high bio load tank. It is filled with 2.5 liters of Sechem DeNitrate. It is maintaining about 30 - 40 ppm of nitrates. I added the second to the same tank with the same filter media in the hopes ...Read More

We will see if the nitrates go lower.Hide
