White glaze over eyes?

ok, it could be that they have reached their max point where their bio loads have increased to a max level, or the other fish could have. Whatever the case, I am sure the water changes being moved up a notch will address the problem.
 
It could have been caused by a little bump on the eye during some aggressive pecking and chasing, and if so, increasing the water changes a bit will be good for the healing of that too. Cloudy eye would more than likely affect both eyes and probably more than just one discus.
 
I will increase the water changes; can't hurt especially if his eye is hurt. Yes the bio load may impede his healing process and could make it worse for his eye. Thanks for the advice. :)
 
These fish have been in this 55 gallon tank for a year and I have been doing a water change 1/3 to 1/2 once a week for a year, I use a Cascade 1000 water filter, I will keep a close check on them, if I have to I will increase the changes.
Let's rephrase "all is well" lets say parameter wise water is 0 for Nitrates, 0 for Nitrites, 0 for Ammonia, PH is 6.4. Live plants. Changed water 1/3 yesterday which I change once a week. The other discus so far don't seem to have this problem.

I'm not saying your test is wrong, but it's very unusual to have '0' ppm nitrAtes with just a 30-50% weekly water change in a tank that's been set up for a full year. You should have a reading of nitrates in a cycled tank. I do 3 times the water changes you do and my nitrates are about 5 ppm. Just curious is all.
 
Had my Blue diamond female for 14 months.Half the time her eyes are dark and hazy the other half time they are yellow.Relaxed as any Discus I`ve ever seen seen.Dunno just fiquered she`s moody.
 
Definetly try to increase the frequency of your water changes. Maybe just do an extra one during the week. It could make a huge difference.

If the cloudy eye is still around, or it is just bothering you, put the particular fish into a quarantine tank and use salt to help heal the eye.
