Pond Size

Knowing how big these Koi fishes can get, they will need a lot of space. You would want to prepare a good area with enough space. Keep the fishes in a pond that is at least 3 feet deep, having at least 50 gallons of water.

If the Koi fishes are still young, they can be kept indoors in an area with at least 30 gallons.

Set up the Pond

The pond must be in a quiet area out of direct sunlight and drafts. You may cover the pond with a hood to reduce the evaporation and that will also keep them from leaping out.

Transfer to the Pond

When transferring new koi to the pond, place the fish bag in the water. This will allow the fish to float in the water inside their bag for about 10 minutes, and the fish can acclimate to the new water temperature.

When transferring new koi to an existing school in a pond, make sure that you quarantine the new fish first in a separate body of water. Allow for 2 to 4 weeks of isolation to be sure they are healthy.

After isolating the fishes and clearing them from any conditions that can possibly infect the existing school in the pond, you may now transfer them to the pond. Use a net to transfer the fish so the old water does not mingle with the new water.

Filtration

Your backyard pond will definitely need proper filtration, and that will include both biological and mechanical filters. Your aquarium filter should be able to process the tank water in 3 to 5 times an hour.

You can also set up a bottom drain, as it will help with water changes.
