Weird. T247 is exactly what I use and I've never bleached a single coral. I also run them at 85/55 but my tank is 30 inches deep and my frag tank (sump) is 22 inches deep. Is your frag tank really shallow?
I wouldn't worry about it since you're having such success with T5.
Yea 10" deep but if I run across a 6x24 ati I'll grab it I thought for sure I could make something happen with the led , I'm not giving up yet
