How old is this setup?
I've done EBay frags, they're always brown. The sellers will claim that they "browned out in shipping" but it takes longer than that. They can make a come back as long as they haven't turned white or shed their skin.
What types of SPS did you purchase?
Also, do you run carbon?
Do you have leathers?
the tank is about 5 months old..
I bought 2 acropora, 1 dendro that hasn't shown any polyps. 1 xmas favia that died, 2 cyphastrea that aren't colored up fully. I do not run carbon and I think I have a "cabbage leather coral" hitchiker growing
