The JBL ProAqua Test NO₃ Nitrate Kit is a professional-grade water testing solution that allows aquarists and pond keepers to monitor nitrate (NO₃) levels with precision and confidence.
Nitrate is a key indicator of water quality — high levels can promote algae growth, while too little nitrate may hinder plant health.

This kit’s advanced compensation method ensures accurate results even in coloured or medicated water, making it a reliable and essential tool for regular water maintenance.

🌿 Why Nitrate Testing Matters

• Excessive Nitrate: Can lead to unwanted algae blooms and reduced oxygen levels.

• Low Nitrate: May limit plant growth in heavily planted tanks.

• Balanced Nitrate Levels: Support healthy aquatic life, clear water, and vibrant plant growth.

Regular monitoring helps detect biological imbalances early, ensuring a stable, thriving ecosystem in your aquarium or pond.
