Wrong Item

I purchased the Tetra Pond Perifier (which works GREAT by the way), and Chewy suggested I also purchase this replacement bulb. Great idea, then I don't have to purchase it later. But...it helps if you suggest a replacement bulb purchase, make sure its the one that FITS the item I purchased. This was the 5 watt bulb. The bulb required is a much bigger one (maybe 9watt). I will have to return it for the correct item.

If you have a koi pond!

If you have a koi pond, you need a UV light!! I bought a house with a koi pond and it was muddy looking. Along with a few chemicals, this cleared it right up!

Expensive bulb that doesn't work

Easy purchase online. Fast shipping. The only problem is that the bulb doesn't work. At first I thought it was because you can't see the UV light in the daytime. Then when I went out at night I thought I could see if it was working. Still couldn't see anything. Figured I'd give it some time to clear up the water in the pond like the last bulb always kept it but still no change in water. I assume it doesn't work now.
