🐠 11W Waterproof Submersible Lamp for Aquariums and Ponds - Clears Green Algae and Purifies Water (HUV-11) Review

The product removed algae very well from my 40 gallon aquarium. The only problem is that you can't put it directly into the tank. I must have missed it in the product description. I could put it in the back filter to use the product. He cleaned my tank in three days.

So, we don't have an aquarium, but we used it to test emergency drinking water sterilization, and we made UV-C sterilization boxes to sterilize various personal items, such as iPhones, keys, wallets, etc. Dog toys . . Not what it's for, but read about it, UV light kills viruses. Stay healthy and enjoy the video. *** Repeated use will discolor your items. My items are mostly black so that's not a problem, but my debit card turned yellow within a week.***

Firstly they wear out. In fact, they are similar to the lamps used in a solarium. Even if you can see visible light, that doesn't mean UV is as strong as it used to be. If he worked constantly, I would not give him more than 3 months of life. They work really well, I run mine in a hidden area of my swamp 3 hours a day on a timer. This helps inhibit algae growth and also kills any floating parasites in the water column. This lamp must be in a low flow area to function properly and be invisible…

You sent me another item. It was an ultraviolet light meant to disinfect things. The electropoles on the bulb and the power supply are not protected from moisture in any way, you can even see two exposed terminals. If I leave this in the water I will definitely kill all my fish and possibly injure myself. This thing is dangerous. ***Update: I received a replacement for the correct light. I still give it a 1 star rating. I plugged it in and submerged it in the aquarium for about a day and the…

I never write these things, but I felt compelled to do so. The photos I shared were literally a day later. I have combated this tank with water changes, medication and whatnot. but nothing happened. Apparently. It'll be clear for about a day, and then we'll be back in Mountain Dew. Apparently I thought these were simple algae, did a little research and suspected I had phytoplankton. This light produced ADVANCED changes in less than a day. It should only get better with time. Note: These lights…

I bought this because my 120 gallon portion had a very heavy algae bloom that I couldn't get rid of. Luckily I have a sump filter so it wasn't hard to put it in the sump away from the fish. The tank was so green I couldn't even see through it! I didn't notice any changes in this sheet for the first 2 days. Day 3, on day 4 the green got a little less, I could vaguely see the back of the tank and it was still slightly green when it started working on day 4, I did a 60% water change and ALL the…

These UV lamps are great if you know how to use them. Never put them in the same place as your inventory, it will kill them! These lights are designed for lagoons or outside the area where the fish are. In my 600 gallon tank there are 3 of these behind a 3D wall when I look at my stash, in my 135 gallon African tank they are in the swamp. On my '64 it's in a closed overflow. I have to tell you it works when I have time, 3 in my 600 gallon bottle just worked quickly when a serious bacterial…

I've ordered 6 of these in the last year but they've lasted over 4 months I've bought 4 of these in the last 2 months and they all burned out within the first 2 days to 2 weeks On The packaging says they have a one year replacement guarantee if you try to contact the manufacturer or whoever you bought them from for a replacement. They don't send you new ones, they just asked you to send back the broken ones. I'm out of boxes because I didn't think I would have to keep the boxes to return the…

We purchased this UV lamp because harmful bacteria were growing in our 15 gallon tank. It had a cloudy/milky white appearance, which was enough to cause problems for plants that weren't getting enough light. We've tried numerous water changes but it came right back, so we figured a UV sterilizer was the best way to deal with it. We put this bulb in an optional supplemental filter (a Whisper 30 with the filter material removed; it barely fit) and ran it with the filter on the lowest flow setting
