Why Is My Koi Pond Green?

In a koi pond, the presence of green water indicates an excessive amount of algae. While algae are crucial for maintaining a balanced natural ecosystem, it needs to be kept at a moderate level. It plays an important role in the nitrogen cycle by absorbing surplus nutrients, which helps prevent the build up of harmful toxins and maintains good water quality. In small amounts, algae produce oxygen and serve as a food source for koi and other aquatic life. However, if algae grow excessively, they can deplete oxygen levels, putting the health of fish at risk. To effectively manage algae growth and ensure a thriving pond environment, it is beneficial to implement robust filtration systems
