No. It should be around 25-26. But can be from 23-28. Just keep it stable.
I keep mine around 26-27.

Have you made any changes to the tank recently?

If your skimmer overflowed you lucky not to have lost everything. Add some bacteria, stability would be best now.

I think he is saying a skimmer overflowing wouldn't cause the loss of everything.

This has happened to me on several occasions with no losses.

I've seen/heard the opposite end of it only. Skimmer cup half full of the good stuff. Overnight it flows over,the morning everything is looking dead and gone.

Guess tank size,cup contents,time etc all factors to consider.
