If you are talking about stringy or mossy algae, a UV clarifier will not do
anything for you- it only works for "suspended" algae bloom - a bacteria or
sludge eating supplement will help with the first 1, actually both types of
algae - a balanced pond with a bio filter large enough for the pond and your
fish load does what a UV does and more

We have lots of algea and I'm considering a uv clarifier. Any suggestions
on a brand? Aqua and Smart seem to look like good ones. We have a pool
that is 15' x 15' x 30".

thanks,
