Red Flower Anemone

So I purchased this Red Flower Anemone two weeks ago. It was doing great until my controller for my fixture became inop. With that being said it bleached my anemone really bad. What should I do to get its red color back? I spot fed it a bit and it still alive since it does open and close but I don't know what else I should do. Also I am running my lights a lot lower then I normally do.



Here are the before and after pics. Any advice would be great. Thanks.









(It does have some brown though, which is a good sign right?)
