Where to Keep Koi
Koi are kept in ponds that can be made from concrete, Gunite, PVC, butyl rubber liners, fiberglass or natural ponds. What is important is the depth and how much water it holds. The pond should be at least 3 ft. deep and have a minimum of 300 gallons for each fish.
The pond will also need to have a pond pump and filters. One filter will need to filter out the waste products produced by the fish and the other for the ammonia and nitrite. The pond pump acts like an aerator. You will also need a kit that tests the water. As Koi are tropical fish, you may need a water heater depending on where you live as well, especially in temperate climates. The water should be kept at around 65 degrees.
