I am 99% sure that lighting has been upgraded to 4x T5 in that tank. I brought the other thank that came from the same person that made this one. The one in the auction was used for corals and the tank I brought was for fish only, he had them both running together.
I changed the lighting to 4x T5 on my tank.
You can view my tank here, most of the corals were small frags and were fine under 4x T5
