Thanks for everyone's reply.
I do understand I am not ready or this, nor I did order it.
Just on phone with the company , anemone cost me $50. Customer service agent checked my original order and confirmed that u didn't order this. But somehow it got added and shipped. They can't credit me nor can take it back. He said I have 120 watts, by 5 watts/ gallon I am just 30 watts away I should be ok.
I said no I can't keep it. I didn't think my lighting is right. Waiting to talk to manager.
What should I do in the mean time??
I will call LFS
