Aquarium Clean Light，3 W mini &13W Submersible Light with UV Test Card,Aquarium Water Clean Green Clear Waterproof Clean Lamp for Pond,Swimming Pool,Indoor (3W MINI)

It might be an unconventional use but I use mine as a safe alternative disinfectant for my cat's water fountain. The light stays hidden inside the porcelain fountain so my cats are safe and not affected by any direct UV light but the constant water circulation through the now-lit interior keeps the slime at bay and keeps the water in the whole fountain that much cleaner and safer for that much longer. I have two cats and I actually have 2 of the exact same fountain (I love it, I've tried many and it's the best) and every week or two I swap the dirty one for the freshly cleaned one. I then have a week or so to thoroughly clean the one not in use. That way my cats always have clean water and I have a little time before cleaning is absolutely necessary if I get busy or bogged down with work. The sanitizing UV light helps make the 2 week stretches possible and works like a charm. Before the light was added I was disassembling and cleaning every part of the pump and filter set up and would often find a light slimy coating on hidden interior surfaces. Since I've added the light, even the interior surfaces of the pump have remained slime free. I'm very satisfied with the purchase. The construction and waterproofing seem to be of a high quality and I like that it has a built in switch on the cord.

These little UV lights are a really game changer for me. I use them in all of my tanks. They keep algae at bay and help all of my aquariums to maintain crystal clear water. Plus, you can’t beat the price! The oldest ones were purchased 3 years ago and they are still functioning without an issue, so I definitely think they’ve been engineered well. UV light is just like staring into the sun… it’s not good for you to look directly at it for very long, which also holds true for your aquatic critters. When using a UV light, you want water to freely pass around it, so that it can help rid your tank of damaging free-floating organisms (such as algae, bacteria, and parasites) by damaging their dna, so they can’t reproduce. Placement is key, because it needs to avoid being seen AND you don’t want to kill beneficial bacteria in your filter. So, how do I utilize these little lights? I pop them straight into my HOB (hang on back) filters. I also tend to use AquaClear filters, but this trick will work in any HOB filter… which hides them from sight (mine and my fish!). I’ve added a photo of how I place them in my filters. I place them behind the inlet/inflow pipe. This way water flows around the UV light first, then it passes through the filtration media, which houses the majority of the tank’s beneficial bacteria. As you can tell from my photo, it fits nicely and it’s really simple to use… just plug it in and turn it on! There’s an on/off switch on the cord. But there’s really no down side to leaving it on 24/7, which is what I do. And as I said previously… I have some that are still going strong after 3 years. Look at the pictures that I’ve posted… if you’re looking for clarity in your water and you want to reduce potentially harmful pathogens… then just buy one of these right now! I recommend them to anyone who asks how to get rid of algae. They are so worth it!

It’s been a few months and light is holding up and definitely works. Great buy for the price!

This solved my problem of having green water every week. Would give five stars because it works grate but giving four starts because you have to put inside the filter and filter cartridge will not fit. Had to buy different filter and improvise.

This blacklist killed my fish within 24 hours of installing it. Other users have reported the same issue. DO NOT BUY if you want your fish Alive.

Have had this product running in my 29 gallon for 3 days now. It has already cleared up my tank very well. Even all my fish and snails r acting differently, in a very good way. If u want the extra assurance that ur water will stay crystal clear, get a UV light

It does work. It took about a week or two for my 40 gallon tank to clear up. You will need a filter or some type of tube that will allow water flow but also allow no fish through. Which is hard if your like me and your fish had babies so they’re tiny as can be… anyway, if you have a good filter already this will fit in, it’s not a bad idea. Cheap. And it does work as advertised but also as people said, it’ll kill your fish if you expose them to this light. Follow the directions and you’ll be fine. I wish the light was smaller tbh it’s kinda awkwardly fat I had to buy a 5 gallon filter just for it to sit in and not kill my fish

Tank: 29 long with generic hang-on filter, auxiliary sponge filter (used, from local aquarium shop for help with cycling), and generic hood with LED strip. I had MAJOR algae issues prior to using this little gem. Its day 3 now and water looks fantastic. I did approx 30% water change and ran this light along with a fresh filter cartridge. Water is crystal clear. Some warnings: think of this as like chemo therapy for your aquarium. UV-C sterilizer lights can damage your eyes and skin and kill your fish, harm pets etc if you arent careful with exposure. This light cannot shine into or around your tank. It cant go in with the fish. It has to be somewhere with moderate water movement and no risk of exposure to anything else. IE: inside your filter box. Would highly recommend to anyone that wants to get rid of cloudy water without dumping a ton of chemicals in your tank or moving the entire set up.
