It must be the tinkerer in me that keeps me awake at night planning the future pond. I think building the pond is more fun than actually managing the existing pond. So here is my next perfect pond to be built some time in the future when time, money, and energy allow.
Size – fits into 10×20 rectangle
Shape – kidney-ish – or oval but not rectangular.
Depth – 5 feet, mostly in ground
Gallons – 5000 to 6000 gallons
Structure
– Concrete/shotcrete with steep sides and sloped bottom to 2-3 bottom drains, no shelves
– flat and raised rock ledges at top large enough you need an excavator to move.
– small waterfall or possibly Japanese garden style falls between two large rocks to small upper veggie filter
Flush-able Filter system – gravity flow from bottom drains to horizontal flow chamber (endless river concept), 1 or 2 fish safe skimmers
Pumps – external, one for each bottom drain and one for skimmer circuit, 1200-1500 GPH
mid water returns with jets that can be aimed any direction
aeration for filters and pond bottom.
UV on each circuit returning to the pond
And of course 20 perfect Koi to go in it.
