Orange water huh? That's really strange. The only reason I can think of is that the goldfishes color is coming off? I've heard of that before. Is their color fading or are the normal color?
Perhaps, it is from the tank itself... what did you clean it with?
Another thought is: it's part of the cycling? but I've never seen this. The only time my water ever changed color is when I added clear water to my tank it made it turn pink for a couple days.
P.S. I'm going out of town tonight, so I won't be able to respond to you until Monday. We do have a substitute moderator named PHPanzer. If you'd like you can email me at phishie@pethobbyist.com. I will probably be able to check that one time over the weekend. This is not anything that will hurt your fish, so don't be alarmed please.
