Tang with Cloudy Eye

[macman7010]

My Achilles Tang's one eye has gotten cloudy and now has a gray film over it. I am pretty sure he scraped it on some rocks several nights ago when I shut the aquarium cabinet and it spooked him. What is the best way to treat this? I have a hospital tank I can put the fish into if need be, but what is the best treatment for the eye?

Tank Specs:

150 gallon Rimless w/ 35 gallon sump/refuge
Nitrate: 0-5 ppm
Density: 1.026
Temp: 73-75

He is the only tang in the tank and I have been feeding him food infused with Kent Marine Zoe and Brightwell Aquatics Garlic Power. I was hoping clean water and good nutrition would clear the eye up but it seems to be getting worse

1 tablespoon of epsom salt (USP grade) per 5 gals of water. Works great at reducing the swelling and is completely reef safe.

My powder blue has gotten that a couple times.... i normally just give it a week or so and it goes away on its own.
