Using an ultraviolet sterilizer (or clarifiers) means your pond
water will never turn green. There are no longer ugly algae blooms (of
a pea soup hue) in the spring, before your water lilies and aquatic
plants come up, and in the fall, when all the plants die back. In
fact, there is no need to cover up your pond with vegetation so that you can
no longer enjoy your fish! Even shadier ponds can have green water,
but particularly in the sunnier ponds, for us, whether to use a UVC or not,
is not an issue. It's an essential! We do not advocate using
loads of chemicals in our ponds and using a UV alleviates the use of
algaecides and also kills harmful bacteria that infect your fish. Keep
in mind, the UV light will not kill the natural algae that grows on the
sides and the bottom of your pond, nor will it kill "string algae" (blanket
weed). It kills the free-floating algae which is what makes the water
Most UV lights sit out of the water and are connected in-line from the pump
to the filter. We do sell some in-pond systems too. They really
are of little maintenance. If the light bulb works, they work.
At the end of the season, they need to be disconnected and brought in, so
that the quartz sleeve doesn't freeze and crack. Normally a bulb lasts
for two seasons but the older the bulb, the weaker the light becomes.
You only see a slight blue hue around the UV unit at night.
Make sure when
purchasing a UV that the wattage is sufficient for the size of your pond!
No need to empty that green pond. Within 5-10 days the water will
clear and stay that way. This makes pondkeeping a pleasure!

the right UVC for your pond.
