My pond is now 6 years old, and last year was the first I got the anaerobic layer in the bottom few feet of water. This was easy to tell when the kid and I would swim to the bottom to fill up squirt guns with stink water. Also the stains on the chain that holds the float dock showed very clearly where this thermocline resided all summer.

I may simply plow a furrow from the house all the way down to the pond, about 900 feet and bury a vinyl pipe in it before I get the rest of the system. The pond is 1/2 acre, so would the cheapest 1/2 tubing work for this? Any diameter recommendations different from this? I was also thinking of running ethernet cable down there for kid support, power over ethernet, and a web cam. Should I put the wire inside our outside of the pipe?

Thanks!

Im trying to do this in stages to prevent sticker shock, but the largest holdup has been figuring out how to get air with no power down there.
