TAISHAN Aquarium Clean Light，13W & 11W & 9 W & 7 W & 5 W & 3 W Algae Removal Light with Timer,Aquarium Water Clean Green Clear Waterproof Clean Light for Fish Tank,Pond,Swimming Pool

The Amazon delivery person hates me I sure, I get multiple packages daily most days! But I never write reviews. This one I just HAD too! I have spent sooooo much money trying to rid my 60 & 30 gallon tanks of mucky, cloudy water. Water clarification treatments, beneficial bacteria, sludge eating bacteria, water changes, UGH 😩 nothing worked! Then in comes the UV lights. I have a small one inside the filter of my 60 gallon, and a 7-8” one pictured in my 30 gallon (as you can see the smaller tank was much worse). The small bulb is only 1-2” overall, so it wouldn’t fit inside my smaller filter system on my smaller tank. That’s why you see the weird black activated charcoal filter media wrap job I did on it (instructions say to not let the light touch the fish it can cause irritation and damage to their skin) so that is an option if you have a smaller filter. Anyway!!!! These pictures are from only ONE DAY. I didn’t have a chance to snap a pic of the larger tank but I did take the photo seen in my review after a couple hours with the light in it. It was almost the same color water as the smaller tank before!!! The clear water photos are of only 10 or so hours of use of the UV lights. I put them in the night prior when the package arrived, and the After photos are from when I woke up the next morning (today.) I am just absolutely BLOWN AWAY by how well and EXTREMELY FAST these lights worked!!!! If you have an over abundance of bacteria grown, Algae, or just plain cloudy water…. This will hands down be the best purchase you ever made for your Aquariums and fish! I’m not joking. The photos speak for themselves!! Buy it, YESTERDAY! If I had went this route sooner I would’ve saved over $200 in products that just couldn’t get the job done. These UV lights definitely do!!! -Bree Zamora

It worked great for a while. It cleared up the Algie bloom in my small aquarium & it cleared up the white fog in my big aquarium. It was great for about 3 months. It leaked today. I will bury it later.🫩 I still need it so ill get another one , a different brand

Received this item today and immediately went to test it prior to placing it in my reef. First time plugging it in, nothing happened. So I went back and tried to look over the instructions that did not help at all. Plugged it back in to a known functional and safe 120v wall outlet and flicked the switch. I know sometimes UV lights can take a second to flick on. Within 5 seconds i hear a buzzing. I look down at the switch box which is now glowing purplish white...clearly arcing is occurring inside the box. Yank the wire out of the plug by the cord and the box with the switch clearly has burned. The very distinct odor of burnt electrical components is present. Looking more closely at the switch box after this incident. There are some deep marks on the outside of the box indicating it might have already been used and returned. Either way, the item does not work and replacing it with another one of the same brand would not sit right with me. As most things in the aquarium are designed to sit in water as well as plugged in tucked away....I cant justify a product with that risk. That is a recipe for some boiled fish and a burned down house. I wouldn't risk it if I were you.

My new saltwater tank got Dino’s! One of the worst algae types for saltwater but UV light is very effective this little guy made quick work in 6 days my coral and fish are happy. I ran it 24/7 and lower the light schedule fed normally never fully blacked out and still got rid of the Dino’s!

Using a UV light (IN THE FILTER BOX, NOT THE OPEN TANK) does a lot for water clarity. I’ve bought a lot of these because unfortunately they die after like 6 months. I buy from the same listing each time and they die faster and faster each time. I feel like everytime I check on them I’m throwing them away.

This is for the 7W 8 in bulb. First let me start off by saying be patient! I don’t normally leave reviews but oh boy did this thing work! At first I was thinking this thing isn’t doing anything. Put it in my filter on low flow and didn’t really notice a difference in the first day. I went away for a weekend and when I came back I noticed it was a bit lighter. Here we are a week later and I have super clear water!! Here’s a pic on how it looked when I started, how I placed it in my filter, and a video of it a week later!! In my experience it’s a must buy to clear you water. I hope it works for others as it worked for me.

I’ve had this for a few months now and it functions great. I got my tank clear after a water treatment and letting it run for a week it fit perfectly into the filter that I put it into and so I can’t see the light or anything and neither can my fish so far I think it’s a great value for the money

I use this aquarium cleaning light in a small outdoor pond to remove algae and prevent mosquito larvae from developing into mosquitoes. The light worked after I plug it in. No surprise. I have used similar devices over the years. Most last about a year.

Worked for few minutes then it exploded. I don’t recommend it at all
