The Pondmaster UV Sterilizer can be placed outside the pond, and its black color makes it unobtrusive wherever its used. Visible during the day and night from any angle, the soft blue halo shows its working but does not detract from the beauty of your pond. These lights offer great value along with ease of use unsurpassed by any other ultraviolet sterilizer.

When to use a UV Sterilizer: Most Koi keepers will keep their unit(s) on year round. But for small garden ponds you may find that only in the spring, with the combination of longer days and an upsurge in fish activity, is UV necessary. If you do run your UV year-round, it must be protected from frost in a well-ventilated housing. Remember it is important to replace your UV lamps annually for peak performance.
