During the second year, the fish will start to reproduce and the pond will become more populated.

Some fish may take a few days to adjust while others may take only a few minutes.

How long does it take to cycle a koi pond?

The average time to cycle a koi pond is six to eight weeks. This is based on a standard 10,000 gallon pond that is 75% full of water.

For a smaller pond, the time to cycle will be shorter, and for a larger pond, the time to cycle will be longer. The cycle includes the following steps:

1. Remove all fish and plants from the pond.
2. Fill the pond with water to the desired level.
3. Add sufficient fresh water to cover the fish.
4. Allow the pond to settle for two to four days.
5. Check the water level every day and adjust as needed.
6. Add more fresh water if the pond level drops.
7. Wait two to four weeks for the pond to cycle.
8. Add new fish and plants and wait two to four weeks for the cycle to repeat.

How long does new pond syndrome last?

Pond syndrome can last for a few weeks to a few months. It is typically a temporary condition that resolves on its own.

Symptoms may include water discoloration, a decrease in fish populations, and a decrease in the number of aquatic plants.

Some types of sun protection that can be installed on a koi pond include a sunshade, a canopy, or a sun barrier.


To cycle a koi pond, you need to establish a bacterial colony in the pond to convert ammonia to nitrites and then to nitrates. You can do this by adding ammonia to the pond or by adding fish waste.

The bacteria will colonize the filter media and surfaces in the pond. The process can take six weeks to six months.
