#8 is much "over kill". 14 gauge is quite adequate. Make sure you buy the
"direct burial" type wire and route it so you (or the next owner) won't
accidently dig it up, later.

What is the current draw of the aerator? Is a small pump? If it is under
1/2
hp then #8 wire will account for the voltage drop.;

I have a pond about 1000ft. from the house that I'd like to run an
underground wire to for an aerator. Is this too long a distance? If
not what gauge wire should I use?

Thanks. John
