For starters (In rough priority ranking IMHO):

Size, volume, depth, and shape of pond, including any submerged or emergent islands.

Distance from compressor to diffusers and size of pipe/hose used to connect.

Fish species, number, and size present.

Feeding? How much?

Age of pond and existing organic sediment load.
