Koi Fish need shade
You need to plant water plants that can provide shade for 15%-30% of your Pond’s surface. You will need to have some plant life to maintain a healthy ecosystem and provide food for your Pond.
To manage organic waste generated by the system, good filtration is essential. Spray Polyurea Coatings are a better option than liner rolls. You can easily install a bottom drain in this situation with a clean and beautiful-looking pond.
To ensure that your koi and all other animals in the Pond are getting enough oxygen, you need to aerate. This can be done with jets, waterfalls, and shallow streams. Proper aeration is essential if you live in hot areas or have large Fish.
The last thing you want to overlook when designing your koi-pond is water quality. Water quality is determined by water temperature and optimum PH. Ideal water quality is between 39 F and 68 F, with a pH balance between 7.0 and 7.5.
