We Changed the water in the big tank again as I was instructed on a forum. They said to change 75% of it. SO we did. The coudiness is already going way down and there is none in the small tank. I found out I was over feeding them. So now that I know that I can do a little better but I still have a long way to go to learn about these beautiful guys. I do know if I ever get a big pond the next one I want is a platinum koi. They look like sparkling silver stars. Anyway. Here are pictures of the tanks
