Two big factors that determine how quickly to install aeration are clarity of the water and fertility of the water. Clear water of 4-5ft allows light penetration and oxygenation by phytoplankton to most of the bottom (10'-12'). Fertile green water contains lots of microscopic algae cells and when extremely abundant at above 500Kcells/ml will cause dissolved oxygen sags in mid summer. Several days of cloudy weather can result in not enough DO being produced during daylight so an accumulated DO shortage occurs during the night and fish kills can occur in relatively new ponds. However this is very rare in new ponds.
