Too much organic material in your pond or water garden puts algae into overdrive by providing nutrients that cause it to grow. Besides obscuring the beauty of your vividly colored fish, algae rob oxygen from the water and emit noxious contaminants that can kill them.

Ultraviolet (UV) clarifiers work by employing that part of the light spectrum to rid algae of its ability to reproduce. Once destroyed, the microscopically tiny algae form into larger clusters that are easily eliminated by common filtration systems.

Sun-blocking plants and those that provide abundant supplies of oxygen present another easy answer to maintaining a clear water environment for your pond.
