High levels of nitrate in koi fish ponds will contribute to the growth of excessive algae causing a decrease of oxygen which will cause problems to your fish. High levels of nitrate can also cause your water to be with a strange color due to the algae.

Nitrates need to be controlled so that you have a clear water and healthy koi fish. This can be done manually and with the help of special solutions.

• First of all use the test kit you have to test the nitrate levels. Make sure you follow the test instructions.
• Verify if the koi pond filter you have is appropriate for your pond. Make use of activated carbon as a way to filter the water but make sure you replace it regularly to reduce the nitrates.
• Now you need to fill around 10 percent of your pond with tapped or rain water. For instance, in case you have a 1,000 gallon pond you will need to fill it with 100 gallons of water. If you are using tap water make sure you wait at least 24 hours to dechlorinate.
• With the help of a bucket, empty 10% of your koi fish pond. This water can be used to water your garden.
• Fill back the water into the pond. Make sure you keep repeating the process once a week.
• Get more koi fish pond plants. They naturally help in the removal of the nitrates that are in excessive number.
• Do not overfeed your koi fish.

With this simple steps you will keep your nitrate in normal levels and the water will stay clear and your koi fish healthy.
