well it happened... 1/2 acre and 13 ft deep
we didnt put any geothermal pipe in.. we talked a lot about it and decided we didnt want it in the pond.
im thinking about doing a pond pump and dump. we are going to be trenching out to the pond from the house at some point. its about 150 feet away. when we do that ill probably drop a loop of 1.25 hdpe in the hole while im at it.
I just need to figure out a way to get a serviceable "filter" in the pond that wont be in the way of fishing or swimming. im thinking about something that hangs off the bottom of the dock maybe 2-3 feet in the water. im open to ideas.
