Why Test for Nitrates?
Nitrates are the end stage of the nitrogen cycle in ponds. While less toxic than ammonia or nitrite, high nitrate levels can:

• Stimulate unwanted algae growth

• Lead to poor water clarity

• Contribute to long-term fish stress and health problems

By using a Colombo nitrate test kit, you’ll ensure your pond remains balanced, clear, and safe for all aquatic life.

How to Use:

1. Fill the supplied test tube with pond water.

2. Add the required number of reagent drops as per the instructions.

3. Shake gently and compare the water color with the provided chart.

4. Record the nitrate level and repeat regularly to track trends.
