advice
My advice depends on whether the tank is overstocked or not. If it is not overstocked, then just skip feeding today and add a dose of something like Prime to the tank before bed.
Depending on what sort of filters you have, I'd suggest leaving the biowheels in place, they are in air (which is very important to the bacteria) and ought to not dry out overnight if they touch water.
Any other media, in canisters or that otherwise will be underwater with no flow, ought to not be submerged but taken to a plastic bag to be kept damp and exposed to air but not dry out. Forget about adding ammonia, just keep damp and exposed to air, then rinse out before replacing in the tank.
Temperature may not be an issue, for just overnight, oxygen is probably not an issue, unless the tank is overstocked. If you cannot stir the tank once or twice overnight, wave a net through it or take a cup of tank water and pour it from a great height to mix the water well, then you can consider adding a capful or less of H2O2 per 20 gallon tank before you go to bed. But, overnight, the fish are slower and use less oxygen, probably not worth it as H2O2 is dangerous and you don't want to overdose. I know my fish would jump out of their skin if I stirred the tank overnight, they are asleep you know! Really, I'd just plan to wake up early and tend to them then.
