SPS issues... again.

[sphelps]

When I switched to LEDs I pretty much wiped out all my SPS (STN). I think the switch into LEDs is stressful on corals no matter what, even if you start low and ramp up, but how the coral ultimately adjusts depends on the other key ingredients to healthy SPS such as water chem, flow and stability. I started at a low percentage as well but my perimeters were not perfect and although things were doing fine before the LEDs that extra stress pushed them over the edge. All my LPS, clams, zoos, ect. on the other hand handled the transition just fine, a few lost some color but overall still seem healthy and many better than ever.

I think those who had success transitioning to LEDs probably had everything else nailed down pretty well first.
