The pond is essentially a quadrant (sort of fan shaped), built into the slope of the garden and has a waterfall positioned in the square corner. The maximum depth to the bottom drain is 6 feet and a skimmer has also been built into the back wall. Both the bottom drain and skimmer lines feed into their own vortex and are pumped to their individual bead filters (Econobead EB60s) and UVs. Heating for the pond is provided by an Elecro heaterpowered by solar panels.
just what koi keeping should be about!
