White Patches on Fish

I did my regular water change yesterday. 25% water.

Now about 17 hours since the water change the fish seem to be stressed and notice some white patches on some of them.

Anyone know what caused this? And if I should perform another water change or medicate the tank?

can you give a bit more information about your tank and water perameters? a picture of the problem could also help.

the water levels are good.
Amonia 0. ppm and 7.1 PH

I think its because of the Media Change. I just recently added fresh new amonia chips and carbon to my filter.

My camera isn't working but it's like white patches like dusty film.

Some of the fish with the patches are active others are just at the top or bottom of the tank and some have the fins tucked in

have you got a Nitrite test kit as well?

you didn't change all the media in your filters did you?

You need to be sure there is no water quality problems before you medicate a tank.
