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. Last edited by Enigma; 09-12-2012 at 03:36 PM.

If it has 12 lights, I'm assuming you're got the 24-36" "Double Bright" fixture. That's only 0.6W per gallon (based on 20 gallons of water), which is really, really low. A longer light cycle will be a good idea, but your fixture is really going to limit what you can keep for corals.
