Those kessil lights you have now even at 40% are at least double the amount of light you had on the tank before plus your still running the same fixture with the kessils. Your definitely causing a light shock. Get your params double checked as well. To clean is not good as mentioned above, corals need to eat. I have removed my filter sock and I have more polyp extension now than I ever had just to make a point. Take this slow ball game and remove the fluval light and cut back intensity on those new lights.
