Tamus, I see you are in OK. If you can possibly attend the upcoming AKCA annual seminar this year in Tulsa OK June 23-26, you will learn a great deal. There will be seminars and a vendor show. A great opportunityto make new koi pals face to face and have a lot of fun. I agree with the advice I've seen previously. Learn all you can before you commit time and money to a new pond or pond remodeling. The link to the AKCA is
http://www.akca.org/ for more information. My first AKCA seminar was over 8 years ago in Orlando FL. I was like a kid in a candy store and had a fantastic time.
