I can't imagine wanting to swim in water that smells like our koi pond. Our dogs will get a drink from our pond if they are out in the back yard and then come inside and want to get in my lap. It is easy to tell they have been drinking pond water for the smell. It is not real bad but I would not want to swim in that. Maybe a large pond does not have the pond smell.

It's built as a natural filter system, it has a skimmer, pumps, etc. and it has to have a percentage of area for plants and the gravel filter bed.
The big thing is you can't have fish in it, but things like frogs are encouraged.
Some do it with a semi-traditional type pool area so they can use a barracuda pool cleaner.
These are big in europe.

You could do a separate koi pond away from the swimming pond.
