Tech update... I've finished my power source expansion.
I've added a UPS to power my MP40 during a power outage, and the UPS also provides surge protection to all the power going to the tank (via non-battery-backed receptacles).
And of course (as you all know) a UPS sourcing it's power via GFCI provides ZERO GFCI coverage for your tank, as the UPS continues to do it's job when the upstream circuit has tripped
So, what would any OCD person do? I added 4 GFCI outlets AFTER the UPS!! This gives me redundancy also so that a single GFCI nuisance trip cannot shutdown my whole tank!
And I also expanded my ReefKeeper with 2 more PC4's (total of 4, each one on a GFCI outlet, with 1 of them on the UPS), and the NET module for notifications and remote control of the system!
