  • Worth the money and works great
Size: 3W for 5-25 Gallon
Worked great. Tank started out very green and nasty and with in a few days using it the tank was clear. Took a week or two to get it perfect and now it looks great and has stayed that way with minimal time use and it mostly closed. Setup was easy and a good choice for price.

  • Quick and perfect results
Size: 3W for 5-25 Gallon
I had an algae bloom in my aquarium, and suddenly my tank was green and cloudy. In this situation water changes don't help, all they do is provide fresh nutrients and make things worse. The algae is microscopic, there's no way to filter it out of the water. Enter the hygger Aquarium UV Light. I put this device in the aquarium where the water flows pretty well from the filter. I closed the Protective Shield so it wasn't shining its UV light on all my tank critters -- the shield still allows water to flow past the UV light. It only took two days and it had killed all the microscopic algae that had turned my water green. There's no residue, there's no cloudy water, there's no green water. And absolutely zero harm to any of my fish or plants or other critters. Since then I've used its timer to only run a little while each day, just in case something like that happens again. I'm sure it would help if there were any kind of bacterial outbreak too. The water is crystal clear. I suppose I could take it out of the tank, but why? May as well leave it there running a little bit. Have green water in your tank? Buy this. No chemicals, no fuss, quick and perfect results, and long term benefits. I'm very happy with this item, I'm sure you will be too. ... show more

  • Essential
Size: 3W for 5-25 Gallon
Works great for 20 gallon long tanks. I had the start of a green algae bloom that wasn’t getting better after a few weeks of doing 30% water changes every 3 days or so. I bought this and within 24 hours I could see a slight difference. I kept it running for 3-4 days straight until I noticed a plateau of effectiveness. I did another 25-30% water change (I read the dead algae cells could be making water cloudy at this point) and it has been crystal clear since. In fact since owning the tank it’s never looked this nice. Would recommend this product to anyone as an essential component of your tank setup. ... show more

  • Did not work…
Size: 3W for 5-25 Gallon
Did not work. After 2-3 days of use, there was no improvement in the water. It remained as green as it had been before I started using this device.

  • Works so well!
Size: 3W for 5-25 Gallon
This worked so well! I was hopeful but doubtful that it would work. My aquarium had green water algae. At first I was only running it for 4 hours a day. I saw a little improvement, but not significantly improving the issue. So, I changed it to run for the max hours. The water is now so clear and I am impressed! Highly recommend! ... show more

  • Good passive uv solution for algae
Size: 3W for 5-25 Gallon
Added this passive UV filter to my 16 gallon aquarium, where I’ve had a bit of a battle with algae despite many snails and shrimp in the tank. I didn’t need extra flow in the tank, and already have more than enough filtration, so this was the perfect solution. It works with the already existing water currents flowing through and past the light, but shrimp and fish are protected from the uv light (which can kill them) by the shutters. I ran it 24 hrs a day the first week because of the passive flow, but now am down to 12 hrs a day. I think as my shrimp make more headway on the algae I’ll reduce it more. I’d already tried reducing light in the tank, even turning it off for days at a time, with no success, and can’t reduce feeding due to fry in the tank, so UV has been a good option for that in between spot! ... show more

I ordered 2 units. Unfortunately, one was packaged perfectly and the other was not. However, the poorly packaged one surprisingly came with all of its accessories and manuals. The one that was well packaged arrived without the suction cups, without the instruction manual, and with no bubble wrap inside. Now i have to buy what it is missing ... show more

  • Great for small spaces. Nano tanks.
Size: 3W for 5-25 Gallon
This is really good quality and fits great and small Nano tanks or tight spaces. I do like that the cover is removable and a bulb is replaceable. I do think that a little bit of the light transmission is blocked by the cover but overall seems to do well for algae control and parasite control. Did not seem to increase the heat on my aquarium either. Would recommend for people looking for a small space option. ... show more
