  • A MUST HAVE 👌
Size: 5W for 13-40 Gallon
I have an outside aquarium, reflection from pool is directing light to aquarium although its under the lanai. Have been fighting the green algae for a month! I have exotic snails so I definitely didn't want to add chemicals. Even a high powered with good media filter wasn't helping. I also have a pond with a bog system that has a UV light inside of it- water is crystal clear ALWAYS. This uv light is small enough to fit inside of my tank filter. I bought it thinking its got to work the same as my pond bog. To my surprise, it ABSOLUTELY DOES! And my tank is crystal clear as well! So yes, buy this baby! Worth every bit of your sanity when it comes to green tanks! ... show more

  • Amazing little UV!
Size: 5W for 13-40 Gallon
I wish I would have taken before and after photos because this little beast turned my pea green reef tank water crystal clear again. I was very skeptical at first but I really needed a UV for my IM Nuvo Desktop aquarium. After comparing to other products (some cheaper) I felt this was the best one for my aquarium and I will admit... it did not disappoint! I will admit that on the evening of day 2, the water was still pretty green but by the next morning the was was clear. If you want the water to clear up fast then you can't expect any UV to do all of the work otherwise, it will take longer. You have to do your part too. Here is what I did... I placed the UV in the overflow compartment, UV must be completely open. I'd clean the glass 3-4x a day. Changed the filter pads as needed (1-2x a day), I have a surface skimmer so that pad was changed as well. I added new carbon and the light spectrum was lowered and on for only 4hrs a day. I completely covered the aquarium with a thick dark towel at night. The water is crystal clear on the 3rd day. Once the water was clear, I did a 2 gallon water change and cleaned all of the pumps and filters then replaced all of the filter pads and carbon. I reset the timer to 12hrs but will adjust if needed. Water parameters are great and water is still clear. Worth every penny! ... show more

  • Great product
Size: 5W for 13-40 Gallon
After a couple days running 12 hours a day I could definitely tell a difference. My water was not bad, but I could see that it was beginning to appear like it was having some build up. I have a 26 gal tank with 9 freshwater fish mix.

  • Works quickly
Size: 5W for 13-40 Gallon
Cleared the floating algae from my tank quickly. Read the instructions carefully, though. I killed 5 fish by blasting the UV light full strength....

  • Uv sterilizer
Size: 5W for 13-40 Gallon
Would not recommend this product. Had a moderate algae bloom, purchased this uv sterilizer and had it in the tank for 3 weeks. I placed it in a high flow area and the bloom actually got worse. I finally purchased another uv sterilizer and it completely cleared the green water in 4 days. Unfortunately I would not recommend this uv sterilizer. I have used hygger products before and this was the first time I was disappointed. ... show more

  • Clears up within a week!!
Size: 5W for 13-40 Gallon
I love everything I get from this seller. This UV light did miracles!! I had tried everything to get my cloudy/green tank cleared. I was reluctant but it actually worked. It took about a week. Just make sure you use the protective shield and close off completely or the light could kill your fish. It filters your water through it and works like a charm. My tanks looks better than it ever has!!! ... show more

  • Does what it's supposed to
Size: 5W for 13-40 Gallon
Works well, in my 40 gallon. It won't kill any algae growth on the glass, only what's circulating in the water and does a great job with that. The bulb fits into the bottom of the unit inside a glass tube, covered by snap on piece of the outside housing. The glass tube press into a seal into unit, but I do get a small amount of water leaking into the tube. So far it hasn't affected it working. Just need to be aware and disassemble and drain, carefully clean and reassemble. ... show more

  • Should have gotten one with a built-in pump
Size: 5W for 13-40 Gallon
I had a pretty bad bacterial and algae bloom after I reset my aquarium, so I ordered this UV light. After several days there was no improvement. I finally did a little research and found the light needs to be next to water flow, so I moved it next to my filter intake, and then it started working. It cleared the bloom over the next few days. If I had known water needed to flow over it (which, in hindsight, duh, of course it does), I would have ordered a UV filter with a built-in pump. But this did eventually get the job done. ... show more
