Sorry for the late reply, but thanks everyone for your comments!
This system was taken down a few weeks ago due to my schedule being too busy and an impending move across the country at the end of the year. All of the livestock was sold or donated. I was saddened to let go of animals that had become so comfortable in their environment, but I hope they continue to do well in captive environments.
I will not be setting up another reef tank for a couple years due to the likelihood of my moving again within that time. I believe that success with these systems is all about heavy planning and automation, so its not easy just to set something up and break it down again in a short time. Then you have the difficulty of finding people that can actually care for these animals. I want to set up a non-photo system that will still be going strong after 5 years or more. I believe that the secret to keeping harder species like Dendronephthya is food density. The goal in the future for me will be achieving highest food densities while keeping with acceptable water parameters, which are not as strict as people make them out to be. I have some ideas how to make this work, nothing new really but I will try to give my input if anyone else is ready to take the plunge and set up a dedicated non-photo tank.
