A friend of mine is giving away a above ground pool. Its 15-20 across and 4 feet deep. He also told me that it has a special liner that can "stretch" and be up to 6 feet deep. He paid $3,000 for it two years ago. He never gets to use it so he said I could have it. I would love to use it as a pond but I live in nebraska and it gets pretty cold. Would there be anyway to have it heated in the winter to keep fish? I know pond stores here keep their Koi alive year round. Would it that much harder to keep some cichlids and cats or maybe a school of pacu? If its possible then I would like to build a wrap around deck off my house. Thanks
