About this item

  • Clears Water All Season -- The Pond Guy UltraUV Pond Clarifier is the ideal choice for ponds and water gardens that suffer from excessive algae and poor water quality caused by full sun exposure.
  • Eliminate Green Water for Good -- UV clarifier equipment is designed to destroy the ultrafine planktonic algae that causes green water. Ultraviolet light radiation destroys algae’s cellular wall.
  • Vortex Chamber -- The durable vortex design of the UltraUV channels incoming water around the UV bulb several times for maximum exposure before exiting, ensuring crystal clear water all season.
  • Results in as Little as 48 Hours -- The ultraviolet rays clear the water before it exits the unit and proceeds to a biological filter or back to the pond. UV Clarifiers require a properly sized pump.
  • EPA Registered Equipment -- UltraUV pond clarifier is registered with the Environmental Protection Agency for the treatment of small ponds that suffer from excessive algae and poor water quality.

Product Description

Clear pond

Here at The Pond Guy

WE KNOW PONDS!

Our innovative, proven solutions carrying The Pond Guy name are designed, developed and tested in our own labs and ponds to ensure high-quality products that exceed industry standards.

PROTECT & CAMOUFLAGE THE ULTRAUV WITH A TRUEROCK
PROTECT & CAMOUFLAGE THE ULTRAUV WITH A TRUEROCK

Use the optional TrueRock Boulder Cover to camouflage and protect the pond clarifier from the outside elements when placing the unit on the ground. We recommend the Medium Cover to hide model: 13 Watt, 18 Watt and 36 Watt or the Large Boulder Cover for the 55 watt model.

The Pond Guy UltraUV Pond Clarifier

Ideal for ponds up to 5,000 gallons.

The Pond Guy UltraUV Pond Clarifier is an ideal choice for healthy ponds suffering from green or discolored water caused by sun exposure. The UltraUV channels discolored water into the vortex chamber for maximal high output UV light exposure. The ultraviolet rays clears the water before exiting the unit and proceeding to a biological filter or back into the pond. The UltraUV features mounting tabs to secure base to any surface and a viewing window to easily monitor the UV bulb performance.

  • When choosing a pond clarifier, pay attention to the maximum flow rates of your current tubing size and the flow rates of your pump and UltraUV model for optimal results.

It works!!
Had a bad algae bloom in January from heavy rains and turned by pond green. Tried the typical chemicals but they did not work. Installed the it on 1/16 and today 3/16 it’s crystal clear. You have to be a little patient as it does not work as quickly as some of the reviews and description. But it does work!!
Thank you for your feedback

5.0 out of 5 stars Crystal clear water. Blown away!
Reviewed in the United States on May 23, 2022
Delivered on Thursday, installed easily on Friday between our 550 gallon per hour pump and the waterfall. The water in our 2,000 gallon pond with 26 fish was a green semi soupy water. We had been pumping water through a makeshift stand and alternating between two old flannel pillow cases trying to strain out the algae. It strained out a lot but it was a losing battle. After installing the UV clarifier we stared seeing the algae reducing the following morning and each day after was more and more clear. On Monday morning, in four days, the pond water was crystal clear. Blown away!
