Aeration system portion in the pond can often be installed after the pond is full of water. You want the airline and diffuser situated so it can be lifted and or removed every year or two to clean the diffuser. Most all diffusers will form some sort of clogging material that reduces the flow of air out the pores. Just as the air filter on an engine needs to be changed due to clogging the diffuser also needs regular cleaning despite what some companies say about self cleaning. Start each year with a clean diffuser. I often install them so the can be pulled in from shore rather than needing a boat.
