Help and advice on shopping for: Nitrate Reactors

Battle nitrate in your tank

Elevated nitrate levels are an issue that many hobbyists encounter. A nitrate reactor puts bacteria to work for you in the constant battle against nitrate. Check out our range of nitrate reactors from top brands such as Reef Octopus and TMC.

What are nitrate reactors?

A nitrate reactor will help reduce nitrate by increasing anaerobic microorganisms. Beneficial bacteria convert waste to ammonia, nitrite, and finally nitrate, which is less hazardous. The bacteria that work in a traditional biological filter are aerobic, which means they use oxygen to break down trash. These aerobic bacteria can be found on living rock, sand, filtration systems, and other surfaces. Deep within the live rock and sand, however, there are zones where oxygen is scarce, and anaerobic bacteria, which can only function in the absence of oxygen, thrive. These bacteria break down nitrate and eliminate it.

Why is filter media important in a nitrate reactor?

Filter media allows for anaerobic bacteria to easily grow and colonise under the right conditions. The best way to apply filter media is to place it inside of a nitrate reactor and use a small water pump to move water through the reactor. By precisely controlling the flow rate, you’ll be able to create a completely anaerobic chamber where denitrifying bacteria will thrive and constantly lower nitrate levels.

What are the main types of nitrate reactors?

We carry a variety of nitrate reactors from top manufacturers here at Swell UK. The TMC Reef Filter Nano 50 hangs on the rear of the aquarium, but the other reactors must all be placed in a sump beneath the aquarium. They can be employed with nitrate and phosphate removing pellets, activated carbon, or phosphate remover, among other media. The pump is included, but not the media. The Reef Octopus is restricted to a sump beneath the aquarium. It includes a pump, but no media. It's made to work with Reef Octopus Bio Spheres, a nitrate and phosphate-removing pelletised media. The TMC Reef Bio-Gro Algae Reactor is not like the other two. It is a unit in which algae known as Chaetomorpha (or chaeto) are grown to help naturally deplete nitrate levels. These can be placed inside or alongside a sump and contain a low-level LED light to encourage chaeto growth.
