Hi my pond is new to me I have just taken over the care of it! so as you can see I am a novice. My question is how long should I keep my UV lights turned off, I am at the moment treating my Koi for Argulus (fish lice) and will have to treat for two more weeks,and was told to keep them off, the water quality is very good at the moment and I am worried that it will revert to the condition it was in before I took it on. I am treating with Tetrapond and it seems to be working as i have not had and deaths since the medication was started, I would be happy to receive any advice that you can give me. And thank-you in advance. Anna
