I have a 32g tank with soft corals and a moderate amount of fish. My power is more than likely going to go out in the coming days due to a tropical storm. What do you guys recommend for a battery backup?

I have a Red Sea Reef Wave gyre pump and a cheap AC pump for my return pump. I could also get some battery powered air pumps but i’d rather have the main pumps going. Another idea I had was a large power bank but these are expensive…I wouldn’t do this unless someone had good success using one for more than 1-2 days.

Or one of these and add car batteries, by the pair, to extend runtime. Mine has 4 100Ah agm batteries and has ran entire tank( about 700-900w load) for 16-18 hours multiple times. After that generator comes out, 12 days is my record for no power. Nothing died.
