Power out 90 gallon

[TitusStar]

Power has been out for 3 hours and expected to be out another 5-7 hours. I have an air stone battery running in both my 90 and 40 gallon. I am worried the 90 gallon has 10 fish and they will suffer. Thoughts of adding more air stones? I have one just in the center which agitates the surface. The 40 gallon seems fine with a strong air stone!

It sounds like you could use at least one more. That’s what I would do if I was worried.

Previously I also had battery backup for the power heads in the DT
