My reef has been cruising for 3 yrs, then I had that close call. I forget sometimes that the tank is like a space station, very unforgiving.
I think I will install another separate 15 amp GFCI circuit for the tank and place the return pumps, backup heater, and perhaps another chiller and controller on it. Ill keep the powerheads and Apex controller on the the existing circuit. 2 redundant electrical, water flow, temp control and monitoring systems. More safe? Its definitely more expensive, complex and has more gear to maintain (screw up).
The Neptune Apex controller was a safety backup. But when off, all I can see from the smartphone app is a blank page, not what happened to the tank. A motorized webcam could help with that, but a P.I.T.A.
I was thinking of getting a portable generator, but I would still have to be home to start it up and plug the tank into it.
I was thinking of getting a home generator with auto switching, but that wouldnt have helped me if a downstream GFCI tripped. Not to mention the $5K+ price tag.
I guess I could give my neighbors my house keys. Then the house belongs to the REEF TANK and not me. Madness.
If my tank did crash I would have left the hobby. But honestly, more & more Im thinking...what a load off!
