I still consider myself relatively new to this hobby. This past weekend I lost power for 5 hours. Not a big deal, compared to what others lost, but it got me thinking on ways to backup my system. Installing a generator isn't really an option, so I'm looking at UPS battery backup systems as a potential that will provide at least some level of hours of protection.
So, what to backup? Obviously, heater(s), but in terms of maintaining some flow what is preferred? Should I backup my return pump, or allow the sump and fuge to go cold to sacrifice for the tank and just maintain 1 or 2 of the powerheads I have in the DT? The 2 powerheads I could run for far longer than the return pump just based on power consumption.
My return pump is a Mag 7, which according to the specs draws 60W.
Or, I could just run my 2 K2 pumps, which only draw 4.5W each, and get much more duration out of the UPS. Would this be sufficient?
Obviously I'd have to bring the temps in the sump/fuge back up to normal before putting them back online when power returns, but in my mind this is the best option.
Am I on the right path?
