One dead fish a day HELP

[corper]

The fish in my tank are starting to die one per day. Their eyes are going cloudy and they are getting white spots (doesn't look like ich) on their fins an bodies. Even my clowns are sick, the anemone isn't helping. Cleaner shrimp arn't effective. Garlic doesn't work. What should I do.

Recently I added some seaweed. Green and red. The green I have seen in several reef tanks but the red, not so much.

Their also seems to be a whit coating on the fish. Slime coat falling off??
