Yes you should be fine. The UV is only strong enough to clump the
floating algae that cause green water, it isn't strong enough to kill
much bacteria in the water column. I'll add usually because in a pond
your size you would need a 2Kw UV but I doubt if it's that large :-)

Is this your first/only filter? It will take out the floating things
that block your vision but you will need to clean it when the flow
falls. Be aware also that the UV tube looses efficiency and the bulb
needs changing about once a year, you also need to clean the shroud
once in a while to allow the light through.

Best of luck.

Thanks for your advice. Chances are the filter/UV will only be in use when
the water turns green. I got tired of cleaning filters long ago. Around the
pond are a couple 'settling' catch basins baffled with cotton rope. Easy to
rinse at season's end and remarkably efficient at collecting gunk. I scoop
leaves and large debris as needed and let the gunk busters (Ponzyme, Laguna)
do the rest. I try to manage to water quality (hardness, alkalinity and
nutrient levels) to keep the water clear.
