(Mr CDW) sez:
Pond is about 1200 gallons. Running an 1800 Supreme pump encased in lava rock.
About 1/2 runs into a filter and the other half simply flows back into the
pond. I would be installing the UV on this part running into the pond.
Please recommend size and brand of UV.
No amount of bio "stuff" seems to clear the pond until plants take hold late in
August/September so I'm ready to go UV.

Size and brand won't matter much; even a small UV will effectively clarify
it, and the UV wavelengths themselves are generic. So get one with
fittings you like.

I've been running an 18watt (I think) AquaFrog last year and this season
with great success. I like that it was trivial to plumb. Of course, this
means I have an enormous green frog spitting water into the center of my
pond, but as this adds more aeration (on top of two waterfalls and a stream
g), creates a hiding place from birds, and the fish like tickling
themselves in it, this is a "good thing" to me. You may prefer an inline
with big fittings.
