ZOANTHUS LAB - Nitrate Plus - 1000ml

The role of nitrates in reef aquariums

Nitrates ( _NO3- ⁾ are an essential source of nitrogen for the biological functioning of a marine aquarium. They play a role in bacterial metabolism and contribute to the balance between available nutrients and biological export.

In modern ^, highly purified reef systems (efficient skimming, refugiums, phosphate-removing resins, advanced filtration), nitrate levels can become too low. Consistent maintenance of _NO3- levels helps preserve a stable nutrient balance , particularly in tanks with high coral density.

We offer a full range of products to target the main elements of seawater following ICP analysis or manual testing.

A simple, direct and controlled formulation

The Zoanthus Lab – Nitrate solution is prepared from pharmaceutical grade calcium dinitrate tetrahydrate (Ca( _NO3 ) ₂ · _4H2O ) , dissolved in purified water (RO/DI).

This highly soluble inorganic salt guarantees perfect concentration stability and reliable analytical readings. No dyes, stabilizers, or additives are added to ensure precise and measurable correction.

• ✔ Stable inorganic solution
• ✔ Pharmaceutical grade raw material
• ✔ Compatible with modern reef methods
• ✔ Consistent and reproducible ICP results

Concentration and dosage

The solution is formulated according to a precise protocol:

• Concentration: 100 mg/mL of nitrates (NO ₃ ^- )
• Recommended dosage: 1 mL per 100 L of water
• Effect: +1 mg/ ^L of _NO3-
• Gradual correction: adjust according to reliable ICP results and tests

Supplementation should be carefully considered and gradual to avoid any sudden changes in the environment. A phased approach helps maintain the biological stability of the tank. Regular monitoring via ICP analysis remains the most reliable method for maintaining consistent values over the long term.

Zoa Aqua Manager: your smart dosing assistant

Each Zoanthus Lab product can be controlled via our free Zoa Aqua Manager calculator. In just a few seconds, you get a precise and personalized dosage from your ICP analysis (Zoanthus Labs or any other laboratory).

No more manual calculations: enter your water volume, your measured value and your objective, and the system automatically calculates the appropriate correction, with the possibility of progressive dosing for optimal stability.

A tool designed by aquarists, for demanding aquarists.
