Are you sure its clear at night or it just looks clear?? Turn the light on and see if its really clear????
This is a good one....... No ammonia at all?? What do you have in the tank, tank size and do you have any caluerpa in it...

I had cloudy water caused by hard water (too much calcium). Well that was in a FW tank. An RO/DI unit couldn't hurt.
