The filter that you move over will bring all the bacteria you need. If the tank is going to be fallow for a week you should add a couple of flakes of fish food to breakdown and become a source of ammonia to feed the bacteria. It doesn't take much.
I like to go 30 days minimum on QT for a new fish.
I would put a power head in that QT tank and aim it so the surface is rippled to help with the gas exchange. If the pH remains stable (take a reading at the same time each day) then the hood is not a problem. Is the 'hole' along the entire back area of the tank?
Make enough fresh mix to allow for 20% pwc
twice a day if necessary in QT for the first week. That would be a gallon bucket or two at the ready. Keep them covered till needed.
When the cycle is complete in the main tank you want to do a 50% PWC
or a couple of 30% PWCs to that tank.
