Brown Jelly is a bacterial infection and, IMO, a separate issue from your bleaching events. There is no way for any type of lightling to cause a bacterial infection.
yup start fragging all your corals and put your T5's back over that tank. could it be stray electrical causing some of this possibly? or new media or top off water?
The problem is, I believe KLR has multiple issues going on here. His LED fixture might be causing some of his bleaching issues but he said the fixture is only over the center of the tank with many shaded areas on the outer edges. I just find it hard to believe he can't find an area, if this is the case, where LPS will not bleach.For those that think that the LEDs can't be the problem, I completely disagree.
It seems to me (a guy who is semi new to the hobby) that the led's are part of the problem. That isn't saying led's are bad. There are bad fixtures out there, just as there are bad florescent fixtures. I would say LED has a higher number of bad fixtures just because people don't know yet what they are buying into and will buy crap fixtures. I also think that a lot of those corals you listed do better with some nutrients in the water. It may also be something else we are all overlooking. You should not shy away from LED's because of one person thinking that it may be causing problems. What kind of other corals are in the tank that you said were doing fine?
+1No it hasn't. No one is really sure what is going on with KLR's tank. I'm really skeptical that it's his light causing these problems since he has plenty of shaded areas.
+1I completely disagree, at this point everyone's ASSUMING the LED's are the problem...
+1Kelby stick the t5s over that tank and see if it changes or not.... I really doubt it's the LEDs myself personally.... If You wanna believe that and wanna sell your fixture lmk I need one haha...
here is your answer - if it were the lights why would the rest be ok?Yes there is shade but why would the 50+ chalices I already have not bleach directly under the light? and when I add these new chalices they bleach/rtn in the shade?
I'll add some experience here. when i first went LED i bought a couple corals and killed all three. i say I KILLED all three - not the lights. i did not acclimate them properly and underestimated the LEDs. since then I have added many new corals with care and haven't lost any of themThe acclimation to LEDs is the hardest part. Maybe try shading them and shortening your lighting period for a couple weeks?

i do not think it is the lights:
either you have a source problem ie wild caught corals not properly quarentined or tank acclimated before being sold
or you have an acclimation problem, starting low light and slowly increasing
or you have a tank problem that your existing corals have adapted to deal with , but new additions can't
