Emergency O2 solution for power cuts

[schooncw]

My 120 LPS dominant system is overstocked with fish and coral and in my condo, rarely get a power cut but had one recently and fish were gasping after 2-3 hours.
I am looking at hygger product that ONLY comes on if power cuts.
Any suggestions for emergency air in a power cut? I don't use Ecotech.

Get a battery backup like a Jackery or something to run your pumps off of during power outages. I looked at one today @ Costco that would supposedly run a fridge for 2-3 days, I'm not good at electrical maths but I'd bet that would run a DC return pump and some other stuff for a good while.

Thanks. Which model were you looking at? But does it stay off UNTIL a power cut and then turns itself off when power returns?

Idk about that brand but the eco flow does this. When power is on its passing through the unit and maintaining the battery charge; when power cuts it switches to battery (far as I know)

something like this would be sweet.

I have Ecoflow River 3. It normally runs on wall power and only switches to battery when the power goes out. It works great. I also go the extra mile and plug my battery powered airstones into it, so when the River 3 battery dies, the airstones turn on as an extra backup.

I'll take a look and thanks. So your return pump is always plugged into it then?

Yes, either return pump or one of your wavemakers works too, to keep the water oxygenated. That's really the main concern here.

Microsoft Copilot Has been a big help to me in this hobby: "Both Hygger AC/DC pumps behave EXACTLY the way you want​

They plug into a wall outlet.​

They stay OFF while power is on.​

They automatically turn ON when the power cuts.​

They automatically turn OFF again when power returns.​

No cycling, no weird modes, no manual buttons, no surprises.

Just plug in → forget → protected.

This is true for:

• Hygger HG123‑10W (your 120‑gallon reef)
• Hygger HG123‑3W (your 30‑gallon planted)

Both use the same AC/DC auto‑switch design."

A battery-powered air pump is one of the simplest and most reliable solutions. Get one that switches on automatically during a power cut, and keep it tested with fresh batteries—it can make a huge difference in keeping oxygen levels up until the power returns.

That's exactly what the models I posted above are. I've requested info from them but they have not got back to me. Do you have any specific recommendations? I want something for a 120 gallon reef and a 30 gallon freshwater.
