While that does work in principal, it works out very very poorly in practice. There was a product based on that patent, but it was very expensive and tended to leave the pool cloudy in a way that was very difficult to clear up. They eventually took it off the market.

I believe the cya test is a similar (same?) process. Turn the pool cloudy then try to filter it out. Does not sound like it worked very well or they would be billionaires.
