TAISHANAquarium Clean Light, 9W LED, Algae Bloom Cleaner for Fish Tank, Submersible with Timer, Clear Waterproof Clean Lamp for Pond, Swimming Pool

This product is a great product I highly reccomend I have had mine now for almost a couple of years and it still works perfect.

After reading some of the reviews I feel I should emphasize DO NOT PUT THIS BULB IN AN AQUARIUM WITH FISH UNLESS SHROUDED!! IF YOUR FISH ARE EXPOSED TO THE LIGHT YOU ARE HURTING OR KILLING YOUR FISH!I purchased this UV-C bulb for a DIY Aquarium Sanitizer project. I wanted the option of using it as an in-tank sanitizer where fish are present and be able to put the naked bulb in a filter partition so I designed and printed a shroud into which you can insert the bulb. It uses a small water pump and features a helical water channel that significantly increases the exposure time for a better chance of killing viruses and bacteria. I verified that the bulb does emit UV-C light using a banana and a piece of tape. It also emits visible light BUT DO NOT LOOK AT THE LIGHT!! At the time of the first use I had the remnants of a bacteria bloom so the water was a bit cloudy. The water was very clear after 2 days with my DIY Sanitizer running. Now I occasionally put it in overnight as a touch up and even used it when I discovered my guppies had Camallanus worms to kill any larvae drifting in the water.

Plugged this junk in and the bulb didn’t light. Instead, an arc and a fire started in the controller section.If I hadn’t tested and watched it, this could have easily started a fire and burnt my house down.Not only did the item not function, but it was a serious and immediate danger that could have destroyed my home or killed someone.Absolutely DO NOT RECOMMEND this item or any such product produced by this shoddy company.

I struggled fighting green water in my 29 gallon aquarium for months!! I tried chemicals, water changes, new filters wrapping with black trash bags and keeping the light off for a week…you name it, I tried it!! I stumbled across this UV light and had nothing to lose. Clearly the pics say it all!! I simply put it in my filter and turned it onto the 24 hour setting (which could probably be turned down now) and patiently waited. The pics attached are taken one week apart for 3 weeks. On the second week, I did add some water clarifier to get rid of the foggyness but that is the only chemical added since putting in the light. I’m excited to add more fish now that I’ll be able to see them. Definitely a great value for the money and highly recommend!!

There isn’t any mercury in the device. The device has “a high quality quartz ultraviolet lamp tube, which is not filled with mercury.” According to online research: this light is faster than a mercury bulb that takes time to heat up. UVC at 254 doesn’t produce ozone like other UVC under 240nm can. UVC at 254 can make someone go blind for a few days [snow blindness][photokeratitis] can cause burns to the skin if not careful. Do not turn on around people or living things. Mercury bulbs are a lot slower to activate. Don’t look at the light. Safety UV glasses that block 254nm recommended. I purchased such glasses before killing bacteria in the tray of my HVAC system. So far this light was the solution to a bad smelling bacterial problem. I can confirm there is a burnt bacteria smell. After running the light and the AC at the same time. It seems the Endospores opened due to the cold. Making the Bacteria available for UVC destruction. As the institutions indicate. There is a burnt smell that is similar to the bacterial infection that was in the air handler. The infection of my Heat Pump/AC so far seems to have died. Will be leaving the device in there in case of future microbial problems. This is a microorganism killing device. That burns everything that is alive. Including your ⚠️🚫👁️ eyes. I would wear safety glasses 🥽 and have the device behind other 🛡️👀✅ objects [inside my HVAC air handler in the condensate tray] before activating the device. ✅😎

I don't have an aquarium, although I may have one in my future when I get married because my fiancee likes to keep fish. I am attempting to use this to kill bacteria in my gray water sump pump well. For years my family, and I suffered with odors coming up the stairwell to our house from the basement, not knowing where they were coming from. Finally after many attempts at controlling the odor, including venting the air outside, and sealing off the room i finally came across an article that said that sludge accumulates in your gray water sump pump well, and that it has to be completely cleaned out once or twice a year in order to keep the odor causing bacteria in the sludge from stinking up your house. I bought the UV lamp as another way of hopefully killing off these critters before they can start stinking up my house again. I am sure that I will still end up cleaning the sludge out of the sump pump well, because even if it doesn't stink it's a good maintenance practice to prolong the life of the sump pump. I don't have the UV light submerged in the water, because I would probably have to clean it off periodically. The water level is low at times, so most of the wall of the sump well gets exposed to the UV light at times. The only place the bacteria might be able to thrive is at the bottom of the well, or in the shadows made by some of the pipes. I hope this review might help someone else suffering with odor problems in their house.

After only one night in my 40 gallon fish tank, one of my gold fish died, other is damaged on its back. So I moved the light inside filter canister. After a few days, water becomes much clearer than before.
