I can't answer your skimmer question because I don't have that skimmer. But you can download a user manual for BH2000 here:

I am very concerned about the anemone. Not only it's gaping, it is also bleached. There is no such thing as a "white" anemone. Sounds like you mail ordered it without seeing it first. I would call the store and ask for a refund to sell you a bleached anemone without telling you. A bleached anemone sometime can recover but it needs some experience and dedication.
Good luck!
