Hmm...so nothing is doing any better under the blues only, and as soon as you put them under florescent light they bounce back?

Yep, my corals absolutely hate the leds.

Based on advice I received on the other thread I have only the whites going at totally minimum strength, pretty much in the off position almost, barely on. The tank is quite dim, actually you were right in saying the whites would be less intense than the blues only so I went that route.
I'm looking at all the corals I moved to the biocube and they are looking so much better already under a 4 bulb t5 I have mounted over it rather than the stock biocube hood.
One of the duncans is actually starting to sprout the tentacles from its socket and the cinnamon palys are open nice and wide now.
I also got a hit this morning on my 125g that I listed on craigslist but he wants the t5 12 bulb nova extreme fixture as well. I am hesitant to call him back cause if I sell the t5's then I will be sol if I need to go back to them. X, do you think the leds will work out in the end? And if they dont, would a retro fit t5 setup be better than the nova fixture anyways? I guess what I want to know is what would you do? Stick it out or revert back to t5's?

Thanks as always for your input......

IMHO you can acclimate everything eventually to the LEDs. I have my LEDs to 90% whites & 95% blues even with corals that prefer the lower light such as Cyphastrea, mushrooms, sun corals, etc. it's just going to take some patience & time. I think it also helps if the corals you look to buy are already being kept under LEDs. I have picked up pieces that were under LEDs and not even had to light acclimate them. Hope everything works out for you. In the end I bet you will be thankful you did the switch

I would def stick it out with the LEDs. I can't imagine the money you are spending replacing 12 bulbs every 10-12 months. That in and of itself should be enough to keep you pushing forward with LEDs. I can't remember if you did the whole DIY mesh screen lids. But you could always later the mesh so that it blocks some light

I agree. Eventually, the corals will acclimate. I have done it. Some corals and certain anemones took many months though. Like 6 months before I had the units at 100%.

I'd stick it out. The difference between the 4 t5ho unit and LEDs is huge and probably why things aren't opening up like they were. Pretend they are mh for a second to understand what intensity of light is being put out. Now take that and let it penetrate water at double efficiency. This of course isn't an exact, rather a way to understand the vast difference you are dealing with. When I upgraded I burned all of my coral to death not realizing. I'd keep the units turned down and slowly start turning up the LEDs once things start opening up.

Ok, I will trust you guys on this one. lol Gonna sell the nova fixture then.

As far as the corals that are now in the biocube, should I get them healthy again and then add them back at some point? They are still iffy looking, the one duncan still hasnt even peeked out yet and the other is just the tiniest bit out. But the gsp is looking even better and it still looks like crap. :-( I'm guessing it will take several weeks before they are back to the condition they were in.
And what about the large toadstool and other leather I still have in the 180g? Should I leave them in there and hope they get used tot he leds? Also note, I did have screens over the glass tops when I put the leds up and they still went downhill fast.

Idk. I read at some point that you had the whites turned all the way down (10%) and the blues around 40% I believe. I'll agree 100% that LEDs are more efficient and powerful than t5 or MH but I don't see how you could go from a 12 bulb nova extreme to LEDs and lose corals that quick

12 lamp Nova Extreme means 6 lamps per 3 feet, correct? 6 thirty nine watt T5 lamps isn't what I would use for Acropora.

Yep, 36wX12 is what i have. I've grown some SPS in there, mostly higher up though.
Just got a phone call, a guy is coming by to buy the 125g with light and all!!! Very excited! This means I can get the custom stand for the 60g a few months before I thought I could. I sold the guy the whole setup, including the light fixture, so now I am committed to the leds. I am so nervous too, my backup lighting option is going bye bye. I am so sad to see the 125g go, it was an awesome tank.
