Something I forgot to mention... While the UV may give beautifully 'non
pea
soup' water it does nothing to eliminate the wastes from fish/animals/etc.
That is another reason I am so happy with my veggie filter. So even if you
do go the UV route I still think there is more than one reason for a
veggie
filter (removing silt and toxins). By the by, my lone little hyacinth is
already clearing things up (put it in this last Sunday).

YES!!! Very important point. UV clarifiers are NOT filters. If anything they
just contribute to the bioload of the pond.

Hows that. I can think of few things that deposit more bio-load than a
pond full of suspended algae. When it is finally staved of a food
source and dies away, it settles to the bottom of your pond... it is
not, for the most part, consumed by your veggie filters. A sand filter,
however can pull it from the pond.

UV light inhibits the algae from reproducing, that is cutting the
bio-load.
