Steve,
Please, let us know what is your main concern (for given setup)?
Light/Heat/Electricity (in other words what is the main cost to rice your corals?)
My understanding is that if you have greenhouse then evacuated tubes, pipes, pumps, controllers and heat storage are waste of money.
However, it might be an option if you build super insulated building with no glass wall to south which is main heat loss reason during the night or on cludy day.
It looks like too much of everything, what will end up in high investment.
BTW, very interesting topic.
