I need to update my post I didnt give enough info. I was at work and trying to sneak a post in.
Since then I have figured out what I think will work. I have picked up 2 sections of #2 service wire which has 2 hot and 1 ground all the same size. each section is close to 200' total 400 feet, about 200 feet short! so I was thinking of running a smaller ground with just a single strand of the cable but then I realized that I could remove from each 200' role one strand and have enough to run the the full length to the cabin then down to the pond edge, by using 1 for the hot and one for the ground on 120 vac only.

I am still only using the small compressor and it seems to be working fine but I am having trouble with my under ground splices faulting out, it has been very wet here and I lost my circuit to the aerator. I want to pull all the other wire out and put this in the ground, and where there is a splice, I plan on setting a post and leaving the splice in a weather box and also mounting a outlet and a over head light something like a street light if I can which should break every 200'. I think it would look cool and my daughter wouldnt be so spooked at night walking to or from the cabin if the lights were on. I already have the ground rods in so its just a matter of removing the old wire and trench the new it which I am hoping to use the subsoiler and just lay it in as I trench it with the tractor by attaching the wire to the bottom of the cutting head and pulling it as I go. This wire is all direct bury type so it should be ok.

I tried to run a larger pump to try and creat a lazy river type circulation but at 8 amps it was way too much amp draw for what I had.

What do you think?

A little snow, Please!
