Koi can become pets. IMO and lengthy experience, with several decent sized koi in a mud bottom 1/4 acre pond with aeration,, expect it to always be turbid often with visibilities of 12"-14" or less no matter how often you chemically try to make the water clear. Koi do what koi do. If you want a clear water koi pond just build a back yard liner pond of any size that you want plus install appropriate good filtration system.
