ASF - Nitrite Test Kit

SeaTest NO₂ – Nitrite Test Kit for Marine & Freshwater Aquariums

Overview

SeaTest NO₂ is a high-precision nitrite (NO₂) test kit designed to help aquarists monitor and control nitrite levels in marine and freshwater aquariums, as well as ponds. Nitrite is a toxic intermediate compound in the nitrogen cycle, formed when bacteria break down ammonia from fish waste, uneaten food, and decaying organic matter. In a well-functioning aquarium, beneficial bacteria further convert nitrite into nitrate, which is far less harmful. Regular testing is essential, especially during the start-up phase of new tanks when the biological filter is still developing.

Key Features

✔ Accurate Nitrite Monitoring – Helps detect potentially toxic nitrite spikes before they harm aquatic life.
✔ Essential for Water Quality Management – Prevents fish stress, illness, and toxicity caused by high nitrite levels.
✔ Easy-to-Use Test Kit – Includes everything needed for simple and precise nitrite testing.
✔ High-Test Capacity – Provides approximately 140 tests per kit, ensuring long-term monitoring.
✔ Color Chart for Easy Interpretation – Compare test results with a color scale to determine nitrite concentration.
✔ Ideal for New & Established Aquariums – Especially crucial during the cycling phase when bacteria are still developing.

Contents

✔ Test Reagents – Specially formulated solutions for accurate nitrite level detection.
✔ Measuring Cylinder – Ensures precise sample collection and testing.
✔ Color Chart – Provides easy-to-read nitrite level comparisons.
✔ Instruction Manual – Step-by-step guidelines for effective testing.

Usage Instructions

1. Collect a water sample using the provided measuring cylinder.
2. Add the test reagents as per the instructions.
3. Mix and wait for the color to develop.
4. Compare results with the color chart to determine the nitrite concentration.
5. If nitrite levels exceed safe limits, take corrective actions (e.g., water changes, adding beneficial bacteria, reducing feeding).

Recommended Nitrite Levels

• Safe Level: < 0.3 mg/L
• Moderate Risk: 0.3 – 0.5 mg/L (Monitor and take action if sustained)
• Dangerous Level: > 0.5 mg/L (Immediate water change and bacterial booster required)

⚠ Note: High nitrite levels indicate an incomplete nitrogen cycle, often in new tanks or overstocked aquariums. If nitrite is detected, perform a partial water change, add beneficial bacteria, and ensure adequate filtration.

Precautionary Statements (H225 - H226 - H314 - H335)

⚠ Caution: Observe safety precautions when handling test reagents.

• H225 – Highly flammable liquid and vapor.
• H226 – Flammable liquid and vapor.
• H314 – Causes severe skin burns and eye damage.
• H335 – May cause respiratory irritation.

Precautionary Measures

✅ P210 – Keep away from heat, hot surfaces, sparks, open flames, and ignition sources. No smoking.
✅ P260 – Do not breathe dust, fumes, gas, mist, vapors, or spray.
✅ P280 – Wear protective gloves, clothing, eye protection, and face protection.
✅ P303 + P361 + P353 – IF ON SKIN (or hair): Remove contaminated clothing immediately and rinse skin with water/shower.
✅ P305 + P351 + P338 – IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and continue rinsing.
✅ P310 – Immediately call a Poison Center or doctor if irritation persists.
✅ P370 + P378 – In case of fire, use appropriate fire extinguishing methods.
✅ P403 + P235 – Store in a well-ventilated place and keep cool.
