Yeah just find an area in the yard that gets full sun, fill the pond with tap water, add dechlorinator, add some plants that are planted in trays or pots, and let them go. Cover the entire base of the pond with trays/ pots of plants.
I used trays that were about 18 inches x 14 inches x 4 inches high and put clay, garden fertiliser and gravel in them. Starting from the bottom of the tray and working up, I had gravel, lawn fertiliser, clay and more gravel. I plant the plants in that and when the plants were about 18 inches long, I took cuttings that were about 10-12 inches and sold the cuttings. The plants divide at the cut section and produce 2 shoots. Let them grow to 18 inches and take more 10-12 inch cuttings from them.
If you get too many cuttings you can plant them in small pots with gravel and sell them further down the track as rooted potted plants. They sell for more because they have a developed root system and are in pots.
