That size pond comes out to alittle over 3000 US Gal.

Too many variables for you. What do you plan to use for the filtration? Commercial or diy? How much are you willing to spend?

I don't think any of us are able to answer these questions for you. You just need to read and learn as much as you can to design your own pond.

If you post specific questions then we'll be able to help. Good luck.
