Crank it to 82 or 83F...you should keep a bubbler on hand, even if you don't always use one, for situations like this (cycling)...and if your power goes out, a battery-operated air-pump can be a fish saver...the electric are pumps aren't expensive, neither or airstones or airline tubingTemp: 75-77°F
And no bubbler because I moved the sponge filter to QT tank
