White clouds usually mean ammonia, or rather a variety of bacteria that eats ammonia. Please test your ammonia right away, and get ready to do a 50% water change when the results are high.
It doesn't take much ammonia in the water to be lethal, a 20% water change is nothing more than a token.....to get the ammonia down be ready to change a LOT more than that.
