Whenever you change to a new batch of carbon, your water will be polished at a fast rate. Meaning, it will be crystal clear. Add new lights to the mix, and you have yourself a recipe for coral bleaching. Now, what you have to do is turn the valve on your carbon media reactor down to half, and set your T5 lights to 2/3 of your regular light schedule. Your corals will come back in a week or two.
