I have a Tsurumi pump and use an Aqua Ultraviolet. It has a two inch outlet.
I don't off hand know the pump model, but I have a 4,000-5,000 gal pond so
it will be close. Another option though (one I think Ingrid uses) is to use
a slower, separate pump. The slower the water moves through the UV the more
effective it will be and you only have to run it when algae is a problem.
Mine is currently disconnected, but if I hook it back up that is what I am
going to do. I have so much plant life that I haven't had a need for the UV.
I assume you are trying to get rid of green water?

Good luck,
Joe

I decided to buy a UV light as I cannot afford to keep buying bacteria (and
am tired of the hassle). Problem is I have to put it within a foot of my
Tsurumi pump which is the 50 PN 2.75S model. This has a 5400 gph and 2 "
outlet. The line runs 30 feet and then up 3 feet to a waterfall. All of
the UV lights at the local store are for 1" and GPH less than 3000. Does
anyone know of a light that is big enough for this pump?
