I'd say leave it the way you have it. You are not feeding much, and waterchanges just remove the food. As your tests showed, the water was fine (although you could test for ammonia if you want). The algae on the rocks will get to the ammonia hopefully before it gets to the remaining corals... sort of an on-site scrubber. Eventually it will go away, and be replaced by scrubber algae. Come to think of it, maybe some Prime or similar might help... to remove the ammonia before the ammonia can get to the corals.
