beauty of the UV clarifier is that it allows one to have clear water
without really balancing out the nutrient equation. To cheat if you

small pond.

I'm afraid that's always been my argument _against_ using UV - it allows you
to clear the water without fixing the nutrient equation. I can't help
thinking that if you had limited the nutrients in the first place, you
wouldn't have had this problem.
