No way would a birdsnest survive with that light. How long ago was that? The minute you see something not doing well, tell Lee about it and he will make it right. This, or course, is within reason. If you buy a coral and 2 weeks later it starts crapping out, I am sure Lee will tell you to bring it in and either nurse it back to health for you, or give you a credit. Now, if the same thing happens 6 months after your purchase, I don't think there is a LFS that will do anything about it. As a a matter of fact, if you have ever been to Cindy's in Vero, you may have noticed that they have a No Guarantee on anything saltwater.
Lee is a good guy. Talk to him and give him the chance to make it right. He's done it for me countless times (of course, I am a regular at his store).
