I know the more the better.

I know 10x total volume/hr is required.

I know more is prefered.

What I don't know is why...or why exactly....what happens in a power outage that brings quick death?Whats the issue with .. say 5x total volume per hour?I'm honestly asking because I just don't know,not to be silly.

How much is too much?Surely there is a limit.If I had to guess I'd say the clown fish in this video would prefer a little less (pulled from the powerhead mod thread):

Or is that the idea?Push em around to keep em healthy maybe?

I have enough flow,but I don't know why I have so much lol.
 
Reasons for quick deaths during power outage: low PH and little/no dissovled oxyen

There's no upper limit for flow. As long as things don't get blown around in your tank, the higher, the better. There are 4 of reasons (that i can think of right now) why higher is better:

1. Active fish LOVE strong current
2. Water moves around LR (bacteria) more often - more efficient filtration
3. Stable PH
4. Less dead spots
