Garree, there are some commercial filters that have a UV built right into them.

Try a froogle search with the words 'pond filter uv' and see what turns up. But
that said you could just sit tight and wait ---
as the cooler weather of fall will shut down the algae production soon,
hopefully you live in an area that has a crisp cool fall.

Use the winter to research, ask questions and plan the filter to end all
filters using all the algae primer ideas ;-)
