Live Koi Pond

Should I remove my ultraviolet light from my koi pond in the winter? If so, at about what water temperature?

I live in South Carolina and have an ultraviolet light in my koi pond skimmer to keep the water clear in the summer months. Would it be wise to removed it in the winter so it will perhaps last longer? Also, should I turn off my water fall in the winter? Or at minimum not run it 24 hours a day? I have about 3 dozen goldfish and four koi. The water at the deepest part is about 30 inches.

I suggest that you keep everything running. The water fall is important for maintaining the oxygen level in water – you don’t want your fish to die.
