The Pond Test Kit from AquaChek provides you with a combination of tests to easily maintain your pond Nitrite and Nitrate levels, pH, and Buffering Capacity.
Nitrite: Nitrite poisoning is likely the leading cause of fish death next to elevated ammonia levels. If your ammonia levels are not maintained then your nitrite levels are also likely to rist.
Nitrate: Nitrates are not nearly as deadly as heightened ammonia or nitrite levels and even promote plant growth. However, over time high nitrate levels may negatively impact your fish and plants.
pH: Maintaining a proper pH level in your pond is crucial to ensuring the best environment for your pond life.
Buffering Capacity: An adequate Buffering Capacity level prevents sudden pH spikes that can be harmful to pond life, both plants and fish.
For best results you should test the water before introducing fish, and monitor it regularly throughout the year. Weekly testing from mid-spring until early autumn and periodically during the winter is ideal.
