UV question

[fishroomlady]

I run a uv sterilizer on my outdoor pond and was wondering what is the life span of the bulb? I'm assuming it needs to be replaced annually if run 24/7 every day?

Here is the textbook answer:

"The lamps last approximately 10,000 hours. That is why we recommend replacement approximately every 12 - 14 months of continuous operation. After this period, the lamp itself becomes solarized and blocks the rays form entering the water."


Note that I've seen some manufacturers that state their bulbs only last 8000 hours.

thanks! I'll have to figure out the hours of use given the number of months it has been in use. I may be able to get another season out of it.....I had no idea on the length of life of the bulb. Thanks!
