Description

Help keep your pond clear with Tetra’s GreenFree Ultraviolet Pond Clarifier. This device uses ultraviolet light to destroy suspended green algae by targeting the reproductive ability of single-celled algae. Once the algae are destroyed, they are pumped out of the clarifier, clumped and removed by your pond’s filtration system. Tetra’s GreenFree Ultraviolet Pond Clarifier installs in minutes, is easy to use and conceal, and can help remove algae blooms in just 8 days! Every purchase comes with a high-efficiency bulb that can last for up to 11 months, plus a high-clarity quartz glass tube, ¾ inch, 1 inch and 1 ¼ inch ID tubing adapters, as well as a 15-foot power cord. This clarifier is designed for ponds that hold up to 1,800 gallons of water.

    Amazing results!

    By MomAlmighty on Aug 31, 2021

    I had a little 125 gallon pond installed for my Red-eared Sliders last spring and released them into it on July 4th. The summer heat and sun turned the water green and icky despite covering the area with a pergola and multiple turtle safe treatment options. I finally emailed one of the product companies asking "what do I do about this algae?" I got a response, and after they looked at pictures and asked some questions, recommended a UV filter like this one. After doing a little research and reading lots of customer reviews I ordered this from Chewy. One day in saw incredible improvement. In three days the water was crystal clear!

    Glowing Accolades!

    By Pondify on Nov 1, 2021

    I have a pond that has always had an algae and clarity problem. I added this little bigger to the pump line and 2 days later I cleaned a lot of dead algae from the pump filter. Amazing job!!

    Works GREAT

    By Doug on Jul 10, 2021

    Set this up...and the water went from pea green soup to clear as can be in 8 days. I was skeptical, but now true believer.

    It works!!!

    By Teresa on Aug 26, 2020

    I could barely see my goldfish in my outside 600 gal pond. The water and rocks had so much green algae. After installing the UV light and waiting 1 week it was amazingly clear. I could not believe it! Great price. Easy install too. Definitely recommend.

    I can see clearly now

    By riosmom on Jun 27, 2020

    We purchased a new home last year with a small pond and we are still learning the ins and outs of everything. Our UV filter froze and broke over the winter which led us to having the worst algae problem once spring began. (lesson learned) We tried everything- algaefix, giving some fish away, pond vac, muck remover, barley straw, etc until we realized our old UV filter broke. We could barely see 1" into the water it was so thick and green. We ordered this immediately and within a day the water started looking clear again. It's a week since we installed it now and we can see to the bottom of the pond again! Our fish are so happy and we can actually see them now.

    Does exactly what it says!

    By Ness on Aug 24, 2020

    I replaced my bulky Pondmaster water clarifier with this one. Nice...smaller. I did have to buy converters for the inlet/outlet as they were small...but it works great. Algae is GONE...and after maybe 48 hours.

    Problem solved!

    By Judy on Aug 26, 2019

    Our clarifier went down after 8+ years. I never expected Chewy.Com to handle pond items. It arrived just in time and all is good with the pond and the fish are happy again. Thank you Chewy.Com.

    Total game changer

    By Kkautsch15 on Jun 22, 2019

    I can’t even describe what a difference this pond clarifier made. My pond was “Grinch-green” and after about a week, I can see the gills of my fish, the edges Of the stones on the bottom, EVERYTHING is perfectly CLEAR!
