Understood. I have turned the light bars off. When we did PAR readings they were so low, we thought adding these would help bring the par up some. At least 50 points or better. When the par measured 225-250 under the radions was told that was not enough for SPS.I would reduce your percentages across the board. You have 3 powerful fixtures and 4 led light bars so you're likely blasting things. If coral isn't growing for some reason, all that light is going to make the problem worse. I'd venture to say that aside from certain sps, you could keep most of your coral alive and slowly growing with the 2 radions alone. That's why I think you should just go much lower with light and cut out all the variables. You can run a tank with just water changes until stuff starts to take hold and grow. Flow, light, fish poop and replacing calcium and alkalinity will grow coral, so start there and work your way up.
