TAISHANAquarium 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

Easy to use and really effective. Cleared tank in a matter of days we noticed a difference on the second day. Turned it off on the 7th day and have used it periodically for almost 4 years and still working great. Happy with the purchase and seller.

I am ranging from having green water, cloudy water, not too clear water problem all the time (since there is live plant). I try chemical, light schedule, fertile schedule, more water change etc and nothing solve it. This is the last resort and it end up being the salvation I am looking for. Now 100% clear water and no turning back.

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.

I purchased this for a 3 gallon betta fish tank and it worked fantastically. I had algae growing nonstop and I couldn’t get rid of it. I think it took about 3 days for it to be almost gone.Would recommend!

Placed it in my waterfall box and have kept it on continuously for a couple weeks and it cleared up green pond water

Wow! Our fish tank had great test levels but was so murky and even multiple 50% water changes weren't helping. We bought this bulb, put in in our filter and 5 days later it looks amazing! I can't believe this worked -- I bought it because we had nothing to lose and I'm amazed.

This sure made a difference in water clarity in my 5 gallon tank. Within 3 days the water went from cloudy to perfectly clear. Does give off a slight amount of heat but not enough to raise temp more than a degree or two. Only issue I had was the outer glass cover cracked for some reason. The inner UV lamp is fine still but outer glass jacket cracked making it no longer useful. Would be nice if they could increase the strength of the outer glass jacket. Once it cracks you can only silicone it or throw it away.

Awesome bulb! Fits in my 10 gallon filter, well insulated and you can't even tell there's a UV light in the filter. Recieved on Nov. 5th, installed it while having very cloudy water and heavy algae, on Nov. 8th water still very cloudy, decided to do an 80% water change + new filter media, it is now Nov 11th and the water is crystal clear!!! (Usually after a water change by the 3rd day it would turn heavily cloudy, even after a large water change + new filter media as my tank houses 8 freshwater fish, 3 cherry shrimp and 2 mystery snails).All in all, I recommend installing it with at least a 50% water change and you will notice your water staying clear for much longer or not turning cloudy at all.You might think: "Yea but this guy changed all water + filter of course its clear", but in all honesty for some reason my tank even while having shrimp + snails by the 2nd or 3rd day of new water was ALWAYS cloudy.As well please keep in mind, in my 10 gallon filter it fitted pretty snug, I had to push/force it a bit to get it deep in the water stream, so I believe that in a filter of less capacity it will not fit and the suction cup did not fit but it wasn't needed in my case.For reference I use a Top Fin Silentstream 10 filter.

Es pequeña pero poderosa, desinfecta eficientemente y ya tenido buena durabilidad, fácil de instalar
