Aqua 57 Watt Replacement UV Lamp

Installed this uv bulb on my fish pond, and it worked perfectly fine.

100% what I needed and wanted.

After years of using much lower cost 3rd party replacement UV bulbs we bit the bullet and purchased the expensive Ultra original replacement bulb - OUCH!! We had developed a cloudy water/algae problem that wasn’t helped by trying two different off-brand new bulbs. Before installing I tested all bulbs and compared the light intensities. The Ultra brand was obviously much more radiant. Sure enough with this product the cloudy water cleared up in a few weeks.

Perfect fit and replacement bulb for my Nuvo 3000 UV water sterilizer running a 14K gunite pool. Purchased a cheaper “comparable” bulb before this one and there was no comparison. This bulb is exactly what I needed and am very pleased with the purchase.

too expensive

fit to a tee

I have been using UV bulbs for over 10 years in my outside pond. They usually last about a year and I usually have to turn them off during the freezing months or they will die. I just had to replace my bulb as I always know when the water turns murky over night the build has died. I remembered that I bought the bulb from Amazon so I went back to see when I bought it and I was amazed that this bulb lasted over 2 years, actually 2years and a month. Needless to say I quickly purchased the same bulb. Also I had not turned it off in 2 years and it still made it, couldn't ask for more.

We use the Aqua Ultraviolet Lamp in our pond each year except for the winter months. It starts killing algae right away as soon as we turn it on. Our pond stays very clear.
