$10k+ 300 gallon setup for sale

My biggest concern is about my fish. I have a sohal tang, powder blue tang, and a desjardini tang. I have had the sohal and powder blue tangs for about 6 years. The desjardini has been with me for about 3. They are all in excellent health, never had ick, and they get along quite well. Ideally, I would like to donate them to the Loveland Aquarium, where they would be well taken care of and I could still see them from time to time. I would appreciate any advice on how to accomplish than. If that is not possible, I would like them to go to a large tank with an experienced keeper. 

I have some corals that may need some TLC and a large (12"x12") colony of green pocillopora. 

I will consider every reasonable offer. It is hard for me to part with all of this, so somebody taking all the hardware would get a great deal. PM me if interested.
