Ruth, I'm sorry, I did not know you sent me a message. I have no idea how to work this web site. I lost every single coral, every single one when I had a castatrophic nitrate problem. then I accidently did a 100% water change. Yes I still have that light and I would like to trade for corals and especially mushrooms if you are interested. Noreen btw I never even took the light out of the box.
