UV Sterilizers

If you're serious about keeping the best possible water quality for your fish, then using a UV sterilizer is a necessary part of your water quality management routine.

UV sterilizers use the power of ultraviolet light to kill microorganisms suspended in the water. One of the most common problems that is controlled by UV sterilizers is the buildup of floating algae. Ponds contain many types of algae and most are harmless if kept under control. But some forms of algae are prone to growing very rapidly under the right conditions which results in what is called an algal "bloom" that will not only turn the water green, it will quickly deplete the water of dissolved oxygen and suffocate the fish and other aquatic life in your pond.

Most small backyard ponds won't need the industrial grade high intensity UV equipment that is used by professional koi keepers, unless you run a very high fish population. The UV clarifiers made specifically for garden ponds by manufacturers like Tetra, Aqua Ultraviolet and Cal Pump are very affordable and perfect for the permanent control of green water algae. Besides controlling algae, UV sterilizers will also kill harmful bacteria and disease organisms and will help keep your valuable koi in great condition.
