LEDs Causing Algae on Sandbed

[Coralgurl]

I have the same looking algae on my sand as well. I have 2 54w T5's and Vertex Illuminex LED's running. I've been moving my lights different heights off the tank, right now they are lower, but generally sit 6" from top of tank. My tank had been fallow for just over a month, fish added back in last week and over the weekend. I was ghost feeding tank for the shrimp/corals, every few days. I'm just going to tag along on this thread for others input.
