Backup batterys?

I have a 125gal reef with 2 heaters rated for 75 gal each venturi pump for skimmer 3 led light bar things and my sump pump im not sure the exact wattage for each but would somthing like this be sufficient for a few hours in an emergency?

I have one similar and all you need to run is the power head to keep the water moving for oxygenation. Dont try run everything on the tank. 125 gallon tank will keep warm for a while.

Make sure it is a pure sine wave inverter or you can burn up heaters. I know from experience!

The pumps should run on any power supply. You could figure out what the bare minimum you need in a true emergency and only put those on the battery. Like 1 heater, 1 pump and 1 LED. I color coded my power cables with electrical tape so I know which to connect if there is a power outage. Helps a ton if I am out of town and someone else has to do it. Another trick I learned is you can use a lamp timer for the pump to extend battery. It doesn't need to be on all the time.

On a 125g your heater is what 500
Your lights are probably another 400-700 Watts?
You would need a huge battery to run these more than a few minutes tbh.

stick with just a power head or 2 most are only around 20-50 watts, some even lower.

your corals will be fine for a week without light, and you will feel uncomfortably cold in your house before the temperature of your tank drops low enough to effect the fish and corals.
