Powerhead on tank left off, worries?

[splix]

I've got a 6' 125g (72x18x22) with an MP40 on each opposing side. Last night I was moving something and had to turn off one of the power heads. Typically I just put them in feed mode, I dont know why I turned it off. Well, of course I forgot to turn it back on. I found it around 12 hours later this morning.
The other power head was still running, return pump was still running. The far left side of the tank basically got very minimal flow for 12 hours.

Should I be worried?

I was going to give it a few minutes and test ammonia real quick.
I've got a 125g display with another 125g refugium full of live rock so I'm not expecting any ammonia spikes.

Nope, you should be just fine. Things may not be as happy as with both running but nothing significant.

No Worries, I'm confident everything will be Good. Speaking from experience of course!

If you had a problem you would notice heavy breathing in your fish. But I doubt there was much loss of oxygen. Already mentioned coral may look unhappy from change of flow. Good to go.

If you run a skimmer, that also aerates the water. If you want to you could use an airstone but all should be fine.
