This was easy to install in place of my old UV filter. I could easily notice the difference when this was installed within a day. My 1200 gallon Koi pond once again looks beautiful.

I was using algicide and a filter and still could not get rid of the green algae. Installed this ultraviolet light and the water was crystal clear within five days. Don't even have to use the filter anymore. Love it!

I purchased this clarifier as i was tired of bleaching and draining my 130 gallon fountain. I live in The South so green and black stuff growing around you is par for the course. In fact everything grows around here but I digress. At any rate this clarifier works wonderfully, no more bleach and no more draining. I even called the company and they picked up right away and answered my questions. I highly recommend it.

The bulb that came with unit killed algae, cleared pond, for about a month. Replaced bulb with different brand which also cleared the pond but stopped killing after about a month. Replaced with a unit that costs half which worked the rest of the season.
