We have the Tetra Pond unit. Has worked for 6 years. We only run it if
we
get green water...not every year or all the time. Has worked well.
===================
My Tetra UV lights are also about 6 yrs old and we've never yet needed to
replace the bulbs. They're still effective and clear the water in days
(when needed).
