1500 to 2000 gallon pond is in full sunlight. Had problems keeping water clear this past summer. What wattage of UV sterilizer would be needed for this size pond? Does anyone have a Jebao sterilizer and how well does it work?

I think UV's are overrated.

If you've got proper fish load, adequate filtration and marginal plantings, then that's pretty well all you'll need. Water lilies are a great source of "shade", that will reduce the area of the pond that's in "full sunlight".

You're trying to "kill" a problem by throwing money at it. Figure out your underlying cause and remedy that.

You can get a 16 watt one .I have a 9 watt and an 18 watt and only use them in the spring with a small pump that feeds just them .I got mine from topdog seller on ebay for less that 30 dollars with extra bulbs

As Morewater says there are other things you can try that might help reduce platonic algae, however a UV unit is usually the surest quickest way.
I have a 55 watt Jeboa UV and it works fine. I often get a green tinge in the spring when the water starts to warm up and the other algae and plant mater that died off during the winter breaks down and releases nutrients back into the water and the other plants in the pond haven't really started growing yet, so I'll turn my UV unit of for a week or so. The water would clear up on it's own, but it takes a little longer.
Hint: if you do get one get the 55 watt unit, they may say you can use a smaller watt unit on your pond but bigger is better and the cost isn't significantly more.

The main thing you don't want to do is push a lot of water through it fast .The slower the water to them the better they work .I bought a small pump just for the uv 's and it feeds both uv's

I have a 4200 gallon in direct sunlight with a 48 watt system and the results are decent.

I had an 18 watt tetra model that did great. I didn't use it last year but didn't need it due to full lily coverage. Will probably get another similar one for this coming year as mine broke early last year and u don't have the lily anymore.

The term UV Sterilizer or UV Clarifier are often used when talking about these things. The difference between weather they function as a sterilizer or a clarifier is mostly a function of the wattage VS how much water passes through them at a certain rate. A higher wattage will always be in a better position to do both sterilization as well as clarification then a lower watt one would be.
I noticed you used the term UV Sterilizer, perhaps all you need is UV Clarification ???

I brought in 8 Jebao UV units for the garden centre: six of them didn't work, right out of the box. Just a heads up!

Just bumping this thread for the OP. It's a shame to have two threads by the same op with the same question.

I'm not anti-UV and I do encourage it because of the beneficial side of killing some parasites and some bad bacteria but if you aren't doing enough water changes and the algae is blooming, then toss in hyacinths, duckweed and water lettuce...

That will slow down the nitrates.

This is a rather late reply should you have not purchased one. Anyone whoever says UV's are not that good or work marginally, I disagree with. They must be doing something wrong. UV's have no adverse effect on a pond but rather only an upside win win. My water looks like drinking water due to the UV. If you're in a sunny spot, more so. I'm an overkill guy and money wasn't a concern so along with my Aqua 57 watt, I've added a Uvinex 50 watt to my Savio. Algae is non existent but running these properly and not too fast, you kill more than just algae. They then become capable of killing bacteria. To kill fungus or viruses they would have to run too slow but under normal circumstances, you will get a germicidal effect if done properly. These are outdoor ponds and 8 watt or20 watt units are going to be quite ineffective and not worth investing in. For a pond that size, to get results, your looking at a 50 watt.

If you want the truth about UV units, get it from the horse's mouth. Read what one of the leading manufacturers has to say-

You make the whole thing more complicated then necessary Meyer. The OP asked about the use of a uv to clear up his algae problem. The straight truth answer is a resounding YES. We don't all have time or the inclination to shoot for the perfect water conditions to totally avoid algae. You are certainly well meaning I'm sure.

Not really. Comments have been made on this thread attesting to the perceived ability of common pond UV units to kill pathogenic organisms in a pond. This, as the Atlantic Water Garden document supports, is not the case. Here is a chart of exposure levels needed to kill some common aquatic pathogens. These levels are not attainable by the average pond UV unit.

The OP did not ask about the killing of pathogens Meyer.
