Tropic Marin Plus-NP
The Tropic Marin Plus-NP is a liquid nutrient concentrate for reef aquariums that have run low on nitrogen and phosphorus. In ultra-clean systems, corals can pale out, brown, or stall when nutrients drop too far. Plus-NP restores balanced levels of phosphate, organic and inorganic nitrogen compounds, and an organic carbon source, so soft corals, LPS, and SPS can recover healthy color and growth. Part of our reef additives and supplements range.
What It Does
- Supplies balanced phosphate, nitrogen compounds, and an organic carbon source in one concentrate.
- Nutrients are organic-bound, so corals take them up efficiently with less nutrient loss to the water.
- Corrects nutrient limitation, the pale or slow-growing look that develops in very low-nutrient tanks.
- Supports soft corals, LPS, and SPS.
How to Dose
- Add 1 mL (one pump) per 100 L / 26 US gallons of system volume daily.
- Continue daily until coloration and growth return to normal, then dose to maintain.
- Do not exceed 1 mL per 26 US gallons per day.
- Test nitrate and phosphate and adjust to your system. Works with manual dosing or a dosing pump.

Frequently Asked Questions
When should I use Plus-NP?
When your nitrate and phosphate read near zero and corals look pale, brown, or slow to grow. It replenishes the nutrients corals need.
Is this for freshwater?
No. Plus-NP is formulated for saltwater reef aquariums.
Will it cause algae?
Dose to your corals' response and keep testing. Plus-NP restores nutrients that are limiting the tank rather than overloading it, so avoid exceeding the recommended dose.
