Low maintenance/automated reef tank?

I’m starting a new reef tank and want to setup a system that is relatively low maintenance/automated. I’ll probably go with a 100-125 gallon tank, but that’s my only bias at this point. Assuming a flexible budget and floor space, what would you do?

[Background: I currently have a Red Sea Max. Corals are growing, and the tank is healthy. However, I’m tired of trying to constantly maintain water parameters (calcium, alkalinity, ph, salinity, temp, etc.). Also, it’s a fairly rigid, integrated system, and I’m looking for something that offers more flexibility.]

Thanks!

 

I would get an aquarium controller, a calcium reactor, and an ATO.

That will simplify things and automate it as well.
