UV Pond Water Clarifier for 10-100 Gallon, UV Light for Green Killing Machine, Swimming Pool, Spa, Large Fish Tank, Cold Plunge, Ultraviolet Clarifier for Green Water

⭐⭐⭐⭐⭐I’m really impressed with this UV light. It comes in a sturdy metal-style housing that feels durable and well-made. You can’t see the light inside, but don’t let that fool you—it’s doing its job. Hookup was simple with my existing pump and hose system, no hassle at all.I was dealing with dark green water in my pond from sun exposure, and within just a few days of using this, the water started clearing up noticeably. Now it’s crystal clear! If you’re struggling with algae or murky water, this is 100% worth it. Highly recommend for anyone fighting green water problems.

This is amazing. My pond was so bad. You could not see anything including my fish. Now after using this light filter my pond is clear as glass. Now you can see the bottom of my pond and everything in it.

In two weeks my pond went from not being able to see my fish to crystal clear with no chemicals!!Well it cleared my water but quit working yesterday ! A lot of money for something to only work two weeks ! I would not recommend buying one !

I bought a uv tube and bulb in one. No pump, so i attached it to my pump by tubing and suction cupped it to the side of my pond, under the water. Never light the bulb unless it is under water. So simple and my pond is happy, the fishes are too. Works great. Oh yea, it has a switch giving option on running time. Mine is on 8 hrs in complete sun and the clarity is awesome. Will deffinetly buy again. The cost is inexpensive. The product is top notch!

Pics are from day 1, day 2, and day 4, only reason im not giving 5 stars is because assembly without leakage was a bit of a pain i ended up using a little silicone on rubber washer and threads to prevent leakage but once i got it sealed up this thing worked waaaay better than expected! My pond is approximately 150 gallons and in direct sunlight all afternoon in arizona and once temps hit above 80 my pond was so green i couldn't see the fish at all, i tried algea fix and barely straw first but nothing could keep up with the algea growth, once i got this thing up and running i saw results very quickly, by day 4 it was crystal clear and fish seem happy and healthy. Definitely worth a try if you are fighting algea in your pond

Functionality:I am on my third type of filter for a 150-gal fish pond and waterfall in my backyard. Since this is only the light and is easily installed on my pump line to the fountain (took about 10 minutes), there aren't any moving parts to break or wear out. We emptied the pond and cleaned it out before installing the light. It has been in place for 2 months now, and the water is staying clean without having to add any chemicals. This is worth the money and I would highly recommend it.

I ran this light nonstop for 4 days in my 650 gal pond. Started with murky green water and ended up nearly perfectly clear. I'm very happy with the results

I've had about 15 different UV pond lights over the past few decades.This one is junk.First off, it leaks horribly fresh out of the box. I loaded it with thread tape and still couldn't get the leak to stop completely.Second, after about 30 hours of use, it began tripping the GFI. So there is obviously a short being caused by water getting to the ballast. (Judging by its design, the is 100% plausible.)I ordered it sooner than I needed it, so of course, by the time I got around to using it, the return window had expired.I 'may' be able to rig it up so it doesn't short anymore, (Fingers crossed) but it will be a permanent fix that won't allow me to change the UV bulb once it goes bad. Either way, out of the box, this thing is junk. Do not buy.
