A 1000 gals. per would be nice.

Are they for grow out or long term?

30 adult Koi would need a very large pond.

Take a look at this link:

I am not sure if this would work but i have herd you need 100 gal per koi, but if you have Japanese koi you would need probably more due to the fact that they get very large if raised correctly. Other types of koi such as from korea and other places like that only reach 24 to 24.5" and stay relatively smaller.

Well, I have 60 koi, the smallest is 18". They are in a 10,000 gallon pond. I two huge filters with two 8000 gallon an hour pumps and I run aerators. They have never gotten sick. They have grown steadily every year. I keep them out there all year (michigan). I don't have an algae problem. I don't use any chemicals. This is not the setup I would recommend for someone who does not want to do a lot of maintenance. It would be perfect for half that many.
