Deltec NFP Nitrate Reactor – Advanced Biological Nitrate Control
Take control of persistent nitrate problems with the Deltec NFP Nitrate Reactor. Developed for marine aquariums, this specialist biological filter encourages naturally occurring bacteria to break down nitrate, providing a dedicated solution for systems where conventional filtration and water changes alone struggle to maintain the desired levels.
How Does a Nitrate Reactor Work?
Unlike phosphate reactors or standard media filters, the NFP creates low-oxygen conditions in which denitrifying bacteria can convert nitrate into nitrogen gas. A specially formulated carbon source feeds these bacteria, while controlled water movement gives the biological process time to take place.
Once established and correctly adjusted, the reactor can provide ongoing nitrate reduction without relying on large quantities of disposable filtration media.
Designed for Reliable Performance
-
Recirculating Design: Distributes aquarium water and the carbon source throughout the reactor, supporting consistent biological activity.
-
Controlled Outlet Flow: Allows water to pass through the filter at a suitable rate for denitrification.
-
Flexible Carbon Feeding: Supports manual or automated operation, depending on the installation.
-
Accessible Construction: Makes routine inspection, cleaning and maintenance more convenient.
A Practical Solution for High-Nutrient Systems
The Deltec NFP is particularly useful for heavily stocked fish-only aquariums and reef systems where feeding and livestock produce substantial nitrate. By targeting nitrate through a dedicated biological process, it can complement protein skimming, mechanical filtration and regular maintenance.
Biological nitrate reduction takes time to establish. The reactor must be run in and monitored carefully, with carbon dosing and outlet flow adjusted according to the manufacturer's instructions. Regular nitrate testing is essential, and the system should never be treated as an instant solution.
Flexible Installation and Model Choice
Deltec NFP reactors can be installed in or outside a suitable sump, offering flexibility when aquarium cabinet space is limited.
The range includes models for different aquarium sizes and nutrient loads. Consult the Technical Information tab when selecting the correct version.
Why Choose Deltec NFP?
For aquarists seeking long-term control of elevated nitrate, the Deltec NFP offers a purpose-built alternative to conventional chemical media filtration. Its recirculating design and controlled carbon feeding make it a valuable option for demanding marine systems.
Available from Rock ’N’ Critters.
Use only the recommended nitrate nutrient solution and follow Deltec's operating instructions.
