Colombo Nitrite NO2 / Nitrate Test Kit

Colombo Nitrite / Nitrate Test Kit — Precise Pond Water Monitoring

Maintain crystal-clear pond water and protect your fish with the Colombo Nitrite / Nitrate Test Kit — a highly sensitive drop-test kit designed for accurate nitrite (NO₂) and nitrate (NO₃) testing in ponds.

Key Features & Benefits:

• Professional-grade drop test for precise NO₂ (nitrite) measurement — ideal for pond keepers, koi enthusiasts, and aquatic hobbyists.

• High sensitivity, capable of detecting low nitrite concentrations, so you catch dangerous rises early.

• Easy to use — comes with visual, step-by-step instructions and color reference charts to simplify result interpretation.

• Complete kit includes test tubes and reagents, enough for up to 40 tests of nitrite levels.

• Fast results — measure within minutes and take action to maintain safe water chemistry.

• Essential for pond maintenance — monitoring nitrite ensures a healthy nitrogen cycle, reduces fish stress, and lowers risk of toxicity.

Why This Test Kit Matters:
Nitrite is a critical water parameter: even moderately elevated NO₂ levels can harm fish before they show symptoms. Using a reliable pond nitrite / nitrate test kit means you’re proactively managing water quality, especially during seasonal changes, feeding spikes, or after adding new fish or plants.

How to Use:

1. Collect a pond water sample in the included test tube.

2. Add the specified number of reagent drops, following the visual guide.

3. Compare the resulting color with the chart to determine the nitrite concentration.

4. Repeat periodically to monitor trends and ensure safety.
