This is a totally different beast.
Transitioning from MH/VHO to LEDs is not as simple as swapping the lights out n matching spectrum it seems. I've read of a few successful swaps but most people who try go back.
It's not that LEDs are no good, it's different and while you or me may not see the difference, coral definitely can.
I think most who try see a stagnation or even some regression depending on how sensitive the coral is. At that stage most switch back (usually this is when they post how bad LEDs are n MH/T5 ftw). But I think if they tough it out, the coral will eventually adapt n be back to where they were before.
But I'll let someone who has personal experience give you their take.
If this was a new setup, that's different.
