The goal is not sterile water, obviouslu that's a non-starter. The goal is
to kill as many algae cells suspended in the water as possible. Even if you're
an optimal aquarist in the Dupla sense of the work a UV sterilizer helps and
makes the most crystal clear water you've ever seen. It probably won't do this
in a pond, but it'll get you closer.
