Backup Battery?

[Kungpaoshizi]

The Ecotech b/u is more amp-hours than the jebao. A lot of computer UPS units though have less amp-hours than the Ecotech battery, so that's the less-desirable choice imo.(and I do IT work, so I've worked with many) The vortech's also let you set the % to spin down to in the case the battery source is activated. Set it to 10% and it's a few watts compared to the jebao that keeps the % running, and then just applies battery.
Get an inverter+charger+switch and pair it with AGM batteries, then you can add more batteries if you need more runtime. Alternatively you could go with a generator or a full house generator. Though imo inverter/battery combos are better because you don't have to worry about fuel and they seem more reliable. (can't even count the number of reviews I've seen about generators that they went to start it 6 months later and it won't start)
Or you could also get a usb battery backup and a usb pump.

Forgive me if I'm ignorant (getting back in after being out) in a power outage isn't he priority temperature and flow (probably in that order)? There for the ups should support both Heaters and powerheads? OP started with prioritizing the return pump.

I'm building basement sump and will probably just have ups at the DT

Depends on the climate, of course, but oxygen is depleted more quickly in a well stocked system than heat is lost. Water has a high specific heat capacity and will retain its temperature even as the livestock use up dissolved oxygen. One point is that we are equating flow with aeration when, in reality, aeration is what's most important. Flow will disperse oxygenated water and help prevent localized deviations in pH, but the assumption is that the water is well-oxygenated to begin with.

So is the airstone backup the best option for low power needs?

Depends on the tank size, capacity of the air pump, and duration of the outage you need to make it through. The air stone option is certainly the low power option, but I can't say it's the best. The air stone option works well for small tanks, but I can't believe one gets adequate circulation with an air stone only in larger tanks. Also, if you have a sump with living organisms in it, you will probably need to circulate and aerate it as well.

Personally, I would use a combination of aeration and circulation, which is why both my return pump and skimmer are on backup power.

The Ecotech battery is 5x larger then the Jabeo/Icecap. The Ecotech will also automatically lower the speed while the others will not.

There are some UPS with an 18 AH battery which is what the Ecotech has. However they will not run close to the Ecotech and I'm not sure why. I think it has something to do with AC vs DC...

Also, none of these are lithium ion, they are all lead acid battery's

Normally, you'd be right. However, my tank is 150 gallons and we're pretty good at moderating the temperature in here (even with a broken air conditioner.) It would take a while for that amount of water to reach a dangerous point. I've never needed a heater or chiller on it in the entire time we've lived here. The 10-gallon, on the other hand, just got too cold and killed my new fish...you wouldn't think you'd need a heater on a night in JUNE, would you?

As far as flow/aeration, I'm going to use my powerheads rather than the return pump. At a combined 16 watts as opposed to my 100w return, I can have them agitating the surface and circulating the rest for a very long time on a backup.
