Product Description

Maintain a healthy pond environment with the NT Labs Pond Health Check 120 Tests kit. Regular water testing is essential for successful pond keeping, helping to ensure your fish and aquatic plants thrive in safe, balanced water conditions.

This convenient test kit measures the three most important water quality parameters—pH, ammonia and nitrite. Elevated ammonia and nitrite levels can be harmful to pond life, while unstable pH can cause stress to fish. By monitoring these values regularly, you can take action before problems develop.

Results are reported as NH₃-N (ammonia nitrogen) and NO₂-N (nitrite nitrogen), making them directly compatible with recommended safe concentrations for fish and aquatic plants. For users wishing to convert results to ionic concentrations, simply multiply ammonia nitrogen (NH₃-N) readings by 1.21 and nitrite nitrogen (NO₂-N) readings by 3.29.

Whether you're establishing a new pond or maintaining a mature ecosystem, NT Labs Pond Health Check provides a simple and reliable way to monitor water quality throughout the year.
