Hello Brian, this is my dream set up. Ted answered you perfectly. I would add that since Algae is your reason for aeration, it can only be a side benefit of aerating a pond. The algae is there for a reason. Nutrient loading and the pond's ability to assymilate those nutrients is low.
By aerating, you will be suspending the nutrients to the bottom of the pond and locking them up (as long as the sediment oxygen demand is met) so that the algae can not use them as a food source. By adding bacteria, you will add additional animals to tie up those nutrients. Finally, if pond dye such as Black is use, it provides a "Sun Glass" effect on the pond shading the amount of sunlight and reducing the algae's ability to produce chlorophyll.
Best fishes,
