Please help with my Coral Beauty Cloudy eye

[davidchmaus]

Here is the scoop. I have a 20QT tank setup. It cycled for 3 weeks and the parameters are 1.23 A - 0 N - slight N - 10 I have a Fairy Wrasse and a Coral Beauty that has been in there for 2 weeks. (bought from the LFS) I am treating the tank with coppersafe with the recommended dose. I do a 4 gallon water change every other day. The plan is to QT for 6 weeks

I took some pictures two days ago for my sons facebook and the eye looked good (went back and looked at the pics). This morning the one eye is cloudy. Here are pics

I guess my question is, what do I do?

Some other questions are

1. What caused it?
2. Do I treat with medication and will the coppersafe be a issue with another medication?
3. If I treat will it affect the Wrasse.

Thanks so much for your time! My son and I are just trying to do things right.

btw any white spots you see are either on the glass or free floating in the tank
