How do I test my koi pond water?

Koi pond water can be tested for a variety of factors, including levels of ammonia, nitrite, and nitrate. Ammonia is a by-product of bacteria that lives in the pond, and can be dangerous to your koi if levels are high.

Nitrite is a by-product of the nitrogen cycle and can cause green algae to grow. Nitrate is a more serious concern, as high levels can lead to fish deaths.

To test your pond water, first check the PH level. Koi like water with a pH of 7.0-7.4. Next, test for ammonia and nitrite levels.

Ammonia levels should be below 0.5 mg/L, and nitrite levels should be below 0.25 mg/L. To test for nitrate levels, dissolve a small amount of nitrate in a glass of water and add it to the pond. If the level of nitrate is high, you may want to do some water changes to reduce the amount of nitrogen in the pond.
