I am not suggesting we are hurting them (although many of you have your LEDs dialed back quite a ways to not blast them). I am just saying that these corals are also colorful in the wild under white light. At depth they all look pretty much blue . It just seems they are growing with less light than we hit them with artificially. I use to believe the more light the better, this isn't true, it's just the right amount at the right frequencies. Too much and they bleach, too little and they grow additional algae to help make up the difference. But if you deplete phosphates by using something like Phosguard. I found the coral became even easier to bleach under lighting it once loved. Drat, this can be like balancing a ball even after all these years. It think I may just let her rip and hope for the best. I worry too much.
