I have recently completed my 5.5 acre pond. I am learning the importance of having a good aeration system and thinking I may still have time to get it installed before the pond begins to fill. I was considering trenching in the air line now to avoid having to purchase an excessive amount of weighted line. Is that a good idea? I'm thinking I would need to leave enough slack to get the diffusers to the surface for maintenance? My pond has a general Hour Glass shape with max 16' depth in front of the dam, but probably averages 4'-12' everywhere else. Some of my questions are, How many Diffusers? Where should they be placed? What depth would be the most efficient? How far can I run the air lines? What size air line? (I'm guessing depends on distance from pump?) What type of pump? I have access to electricity on the property and could get it to the edge of the pond if necessary. Any experts out there willing to take a stab at what I might need?

Thanks in advance for any suggestions or advice.
