I ran a small 9W pond UV for months some years ago without any positive effect.
To buy a 80W UV for a test does not appeal to me since they are expensive.

I disagree and so do many of the others who have tried it. I have a massive 12 foot skimmer with dual recirculating penductors running off a dolphin 6000 pump. It's a massive beast that can run on a pool. I had dinos on the tank it was on until I installed a slow flow UV. In a day, I saw results.
