Which Marineland LED are you using? The Reef Bright one (the stronger of the two) only has 1W LEDs. That's only 23W over a 24"-36" tank. That is not a lot of light. You may very well need to run a longer light cycle: even to keep softies and LPS. You won't be keeping SPS with that light.
I have a 36" four bulb T5 fixture over my 40 breeder, and I need to run a 12 hour light cycle to keep SPS from going completely brown on me.
Edit: Sorry. I should say that you "probably" won't be keeping SPS with that light. Most will be a no-go, but a handful might do okay.
