I think the show was called Poolmasters. There were a few other interesting ones called Aquascape Pond Squad, and Insane Pools Off the Deep End that are fun to watch and get creative ideas from (but not as a tutorial on building sustainable pools). I love following David Pagan Butlers work. So much good info for the sustainable swimming ponds/pools, best I've seen on the subject.
I just cut ground two months ago on my own natural swimming pond based on David's work. When I'm finished with that I intend on building a smaller natural fish pond to raise tilapia in.
