Biological filtration primarily focuses on removing toxic ammonia and nitrite from the water. Ammonia is a waste product from fish excretion and decomposing organic matter. It is highly toxic to Koi and can cause severe health issues or death. Beneficial bacteria, such as Nitrosomonas and Nitrobacter, convert ammonia into nitrite and then nitrite into less harmful nitrate, respectively. This process is known as the nitrogen cycle.

The nitrogen cycle involves several steps:
1. Ammonia Production: Fish waste and uneaten food generate ammonia in the water.
2. Conversion to Nitrite: Nitrosomonas bacteria convert ammonia to nitrite.
3. Conversion to Nitrate: Nitrobacter bacteria convert nitrite to nitrate.
4. Nitrate Removal: Nitrate can be further reduced through water changes or utilized by aquatic plants.

Specific conditions that affect biological filtration include overstocking the pond, poor water quality, and inadequate filtration systems. For example, too many Koi can lead to excess waste production, overwhelming the beneficial bacteria. Similarly, contaminated or stagnant water can hinder bacterial growth, disrupting the nitrogen cycle.

Maintaining optimal water parameters, such as ammonia, nitrite, and nitrate levels, is crucial. Regular monitoring and established water changes help maintain a healthy environment for Koi.
