badbuck,
If you want to aerate to keep your water cooler, you might consider aerating in shallow water, about 4 or 5 ft deep at night. I have a 1 acre trout pond, and am using an Ecoplus Air 5 linear pump with a 70 ft. soaker hose. I filled a garden hose with sand and zip tied it to the soaker hose to keep it weighted down, it's working great, and i run it from 10pm to 6am. Total cost with hose about $115.00
Just my 2cents worth, you'll probably get lots of expert info soon, good luck.
