Thoughts on keeping bacteria alive during an outage

[gregzz4]

My DT is covered (although my sump is not)
But the the topic of this thread is my QT

I have a battery backup air pump that turns on automatically in the event of an outage

My problem is, I tend to over-think things sometimes (most times ) and now am wondering if, besides an air stone in the tank, should I put one in the HOB filter ?
I know it'll fill the space with air bubbles, but I want to keep the bacteria in the sponges alive

What are your thoughts or knowledge ?
