ELOS NO₃ Test Kit – Nitrate Test for Marine & Reef Aquariums

Accurate Nitrate Testing for Stable Reef Systems

The ELOS NO₃ Test Kit is a high-precision nitrate test designed for marine and reef aquariums. Maintaining stable nitrate levels is essential for coral coloration, controlled nutrient balance, and long-term biological stability.

Unlike low-quality test kits that produce inconsistent color shifts, ELOS reagents are manufactured to deliver clear, repeatable, and reliable results, helping reef keepers make informed decisions instead of guessing.

Why Nitrate Testing Matters

Nitrate (NO₃) plays a major role in reef systems.

If nitrate is too low:

• Coral growth may stall

• Pale or pastel coloration can appear

• Biological instability may develop

If nitrate is too high:

• Algae growth increases

• Coral coloration darkens

• Long-term stress and reduced vitality can occur

Balanced nitrate levels are key to nutrient control, especially in modern LED-lit reef aquariums.

Key Features

• Designed specifically for marine aquariums

• Clear and easy-to-read color comparison

• High-quality, laboratory-grade reagents

• Repeatable and consistent results

• Suitable for reef, fish-only, and mixed systems

• Ideal for SPS, LPS, and soft coral aquariums

Typical Nitrate Reference Ranges

These ranges vary depending on system type:

Ultra-low nutrient SPS systems: 1–5 ppm
Mixed reefs: 5–15 ppm
LPS or nutrient-rich systems: 10–25 ppm

The goal is not zero, but stability and consistency.

Directions for Use

• Follow the included instructions carefully

• Use clean test vials

• Add reagents in the correct sequence

• Allow proper reaction time before reading results

• Compare color under neutral lighting conditions

Always rinse test vials with RO/DI water after use to maintain accuracy.

Francois Neo—AquariumPartner Insight

Nitrate testing is not about chasing zero.
It’s about understanding how your system processes nutrients.

In many modern reefs, especially LED-driven systems, nitrate plays a direct role in coral coloration and metabolic balance. Accurate testing allows you to adjust feeding, filtration, and supplementation with confidence.
