The main difference between a skimmer and a UV unit is that the skimmer removes them while the UV leaves them dead in the water for the skimmer to pick up later so a good skimmer seems to be the better choice.

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.
