:( Fish 02) Iam going on a 3 month trip and would appreciate if
someone can help me to set up a system of UPS so that my saltwter reef aquarium can stay up after a power failure for at
least 48 hours
 
48 hrs is tuff, the first thing that comes to mind is aeration, the is a air pump that plugs into elec and when the power goes out it goes on, it say 10-20hrs

next would be temp, if the power goes out ac dont work(DUH), you being from fla, what would the ave day temp be? if its like 95 or so, youre tank will be too,

the only true solution would be a back up generator, so weigh costs,is it cheaper to replace the live stock or get a generator
 
The UPS---just get a big unit and minimize what stays running: a small pump for bubbling is A number 1. Heater won't be a problem and they're the most power hungry. You're probably already above 80 down there...maybe a small chiller with a reliable thermostat might be in order: I'm not sure of their power draw. Lights on timer, NOT connected to UPS. Consult a knowledgeable computer store (triple underline knowledgeable) and read how much wattage over how much time on the UPS label before you buy. They vary widely. Most importantly, a friend with a key who'll show up and check after power comes on again.
Your timers will of course be screwed and will have to be reset, or your critters can just get used to sunlight at 2am: they don't really care. If heat is a serious issue, you might even deliberately reverse day and dark to get the lights in the coolth (relative) of the night.
 
If you're really serious about maintaining everything for 48 hours, here's a link to stationary UPS's. You can order as big a battery bank as you need. They have a selector at the site to help you size the UPS and battery bank.

Or, it'll probably be more practical to install a standby generator, especially if you have gas or oil heat already.

I'm an electrical engineer by profession and frequently call out generators and UPS's for commercial and industrial facilities. If you need help I can probably find you a manufactures rep, or consulting firm in your area.
