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.

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

As Spring came, the light shifted and filled our 15 gal tank with sunlight... meaning there was an explosion of algae. You could barely see the poor fish through the bright green cloud. I remembered using UV back in the day and ordered one of these. Very easy to use, you just pop in the tank but keep in mind, this bulb NEEDS to be in a filter or somewhere that the UV light can't reach the fish or you won't have anything alive in the tank! This little wonder started clearing the green immediately, and although it took 7-10 days to completely turn the water crystal clear again - it's a very effective, non-toxic way to keep your take clear for a long time. Have had it going for over a year now just for maintenance and wouldn't have a tank without one!

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.

Used this for 8 hours/day for 4 days. Green water got greener each day. The included test strip says it's working. I can see the blue light when it's on. The enclosed specification says it operates at 220V. USA uses 120V. That means this 3W bulb only outputs 1.5W; making it useless.

Very strong lamp. I'm using this for disinfecting a table-top humidifier after manual cleaning. It's important to cover the humidifier (towel, cardboard box, etc.) during cleaning to prevent inadvertently viewing the light but it does a much better job than I have ever been able achieve with bleach and manual cleaning. Humidifier goes twice as long or more before showing signs of nasty things. I use the lamp for about an hour with the humidifier empty after manual cleaning.

Let me start by saying my fish tank was in a BAD way! I have a 6 gallon freshwater corner aquarium that is only about 2 months old. My water started slowly turning green and I had no idea what was happening! I've owned a variety of tank sizes and this had never happened before. I eventually consult the internet and find out I had a terrible case of algae bloom! A UV light was strongly recommended as my critters were slowly dying. We lost one guppy and about 5 shrimp! I found this UV light and chose to go with this brand because of reviews and of course, PRICE! It is about 2-3 inches in length and about as wide as a ladie's thumb. It gives off a powerful little glow for such a small thing! It comes with a suction cup so you don't have to worry about the light floating around. It was super easy to plug in and set up! In less than ONE week, this light has completely transformed my tank. It has saved my remaining guppy and shrimp! If you're looking for a reasonably priced UV light that is small but mighty, give this brand a try! You will NOT be disappointed! I've attached progress pictures to show what 6 days of use has done to my filthy tank water!

Only lasted 5 months
