Do you need a UV light for pond?

For new ponds with enough plants and without an extreme amount of fish: If your pond is brand new and has the green pea soup problem, all you might need is some patience. But for ponds without many plants and with a lot of fish, a UV light is most probably recommended from the start.

Also asked, what does UV light do to pond water?

UV lights work when water from your pond is pumped through their light path. The single-celled, free-flowing algae within your pond water is then exposed to these high levels of ultraviolet light. This light destroys their DNA and kills them.

Secondly, what size UV do I need for my pond? Manufacturers recommendations:

Size of pond Wattage
Aqua Uv 5 to 200 gal 8 Watt
200 to 500 gal 15 W
500-1200 gal 25 W
1200 to 2000 gal 40 W

Keeping this in view, how long does it take for a UV light to clear a pond?

Once fully mature, you should notice a difference within one week of turning the U.V.C. on and full clarity should be achieved in two weeks.
