corals and lighting

[prohockey86]

Hey so i keep checking my water and all the levels are perfect. But for some reason my zoos and only my zoos aren't doing well ever since i switched from t5's to leds. Do they prefer brighter light or less light. What techniques can i try to make them open up like they always have.

from my experience, i can tell you that i had to acclimate my tank from halides to leds.
