UV light

I just installed a stand alone UV light in my outdoor mini pond last night and there was a big difference within 24 hours. 80% of the algae is gone. I'm experimenting on ways to control algae because I'm planning to build a bigger pond in the future and I think UV is the way to go.
I believe it is good for any number of things it is all deppendent on the zap or dose that you give with it there are tables that tell you at what zap you kill certain things
When everything else failed to clear a tank, a UV did it in 24 hrs.
Not a thing I would run 24/7, but a handy tool.
Something, that if you can get one for a good price, well worth having.

Thanks for your input. Do you know of any ill effects it might have on water quality or stock if on 24/7? I got mine from Home Depot for $59.99 it's a Beckett 9 watts UV rated for up to 650 gallons.

None that I know of.
There was some discussion about a decline in immune response with fish kept in a UV tank, running 24/7.
From what I recall, it was a "boy in a bubble" type argument.
That if removed from the bubble all forms of bad things could happen.
Thinking was, if fish were added to that environment the currant occupants could be susceptible to disease.
I really couldn`t say.
Remember, a UV`s effectiveness is controlled by watt/gph balance.
Believe most effective rate is 1 watt per 10 gph for bacterial control, with higher gph for things like clarity and algae.

So how big is the tank, and is it indoor or outdoor? Was it cloudy due to algae, or something else?

Couldn't tell the tank size because it's something like an oversized bowl made of plexiglass. It was used as a cover for a candy dispenser machine in an amusement center where I work and I just built a frame to hold it upright. Dimensions: 39" diameter x 20" center height. It's outdoor under a canopy with indirect sunlight. My main problem was green water due to algae and the UV worked in eliminating the problem. Right now it's stocked with guppies for feeders. Here are some pics sorry no pics when it still has green water.

55g with a 10g sump.
This was when I was doing all kinds of changes to filtration.
Both overflow style and sump configuration were in a constant state of change.
Tank got a bacterial bloom that would not go away.
Week after week the tank seemed to clear some after a WC, only to "milky" up again.
I know I was upsetting my toxin munchers with all the changes I was doing.
Came across a mistake in pricing at lowes.
A 9 watt UV unit for a pond.
Originally priced at $129 marked for sale at $9. This was during the winter and all their pond stuff was sale priced.
Confirmed the price with the cashier and away I went.
Rigged it as a HOB and it sat in my sump.
The pump that came with it was 100 GPH, so it was perfect for bacterial work.
I ran it for a few weeks after the tank cleared and then took it off so I could muck around with the filtration some more.
I keep it in the garage now as a “just in case” tool, also for getting the water to that super clear level to show off.
If you already have really good mechanical filtration and think you can`t get your water any clearer, hook one of these up and prepare to be amazed.
