NITROPLEX
The Complete Nitrogen Reduction Consortium — 16 synergistic strains cultured together, delivering full nitrogen-cycle coverage from ammonia oxidation through to aerobic nitrate removal. All in one oxygenated system. No methanol. No anoxic zones. No H₂S risk.

Complete Nitrogen Mitigation. Aerobically.
Most nitrogen-reduction products need anaerobic zones and methanol dosing. Nitroplex works in fully oxygenated systems where traditional denitrification simply cannot operate.
Aerobic Denitrification
Nitroplex uniquely removes ammonia, nitrite AND nitrate in the presence of oxygen. It thrives in oxygen-rich environments — eliminating the risk of hydrogen sulphide production, with no requirement for anoxic zones or dedicated denitrification filters.
Traditional nitrate removal forces you into anaerobic reactors, methanol dosing and the constant danger of a toxic H₂S crash. Nitroplex rewrites that rule: the entire nitrogen cycle — NH₃ → NO₂⁻ → NO₃⁻ → N₂ — driven aerobically, right inside your existing biofilter. This is the single biggest reason to switch.
True Microbial Consortium
16 hand-selected strains cultured together — not blended post-fermentation. This creates the same synergistic community found in a mature, high-performance biofilter.
Pre-Adapted to OC-K Carbon
All strains are grown on OC-K microbial nutrient — biologically derived carbon they already recognise. They transition into your system without lag time, food-source switching, or biomass die-off.
Rapid Waste Assimilation
Accelerates the breakdown of organic nitrogen compounds, releasing bioavailable nutrients while preventing toxic spikes.
Probiotic Stability
Supporting probiotic strains protect the consortium, extend shelf life and maintain functional integrity in the bottle and after dosing. Pair with OC-K for maximum speed and resilience.
Fish or Fishless Cycling
Use with livestock in the system or during fishless cycling. Complete microbiome management for RAS, aquariums, ponds and hatcheries.
A Complete Nitrogen-Cycling Community
Total viable count ≥ 1 × 10¹⁰ CFU/mL — including nitrifying, denitrifying and probiotic CFUs. Sixteen synergistic strains covering every stage of the nitrogen cycle:
NH₃ → NO₂⁻ → NO₃⁻
Full oxidation pathway plus aerobic nitrate reduction — the complete loop in one product.
Microbiome Management
Establishes and maintains a balanced, resilient biofilter ecology that resists crashes.
Faster Maturation
Lower peak ammonia/nitrite/nitrate and faster cycling for new and re-started systems.
Universal Compatibility
Aquaculture biofilters, RAS, aquariums, ponds — freshwater and marine aquatic systems.
Four Steps To A Stable Biofilter
Shake & Dose
Shake well before use. Dose directly into the biofilter, sump, tank or pond water column.
Pause Sterilisers
Turn off devices that remove or kill bacteria — protein skimmers, UV, ozone — for 6 hours so bacteria wake up and colonise. Filter mats & foam can keep running.
Hold Conditions
For best results maintain dissolved oxygen > 4 mg/L and pH 7.0–8.5. Do not mix with strong oxidisers or disinfectants.
Pair With OC-K
Use alongside OC-K for enhanced carbon support. Dose OC-K with Nitroplex during start-up for maximum speed and resilience.
Dosing & Maintenance
Simple dosing for new-system cycling, ongoing maintenance and pond-side culturing.
| Application | Dose | Frequency |
|---|---|---|
| New Systems / Cycle Start | 1 ml per 100 L | Once per week (or as required during cycling) |
| Maintenance / Post-Treatment | 1 ml per 200 L | Once per week (or as required to control nitrate) |
| Enhanced Carbon (with OC-K) | Dose OC-K alongside | During start-up for peak performance |
Maintain DO > 4 mg/L and pH 7.0–8.5. Do not mix with strong oxidisers or disinfectants. Available in 100 ml · 250 ml · 500 ml · 1000 ml.
