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.|
