Achieving a Balanced Pond Eco-System
Although each pond differs in the amount of sun, depth, dimensions, water movements and temperature, the following formula will be helpful in achieving a balance for your pond. For each square yard of surface area you should have:

Water Lilies (One medium to large Water Lily)
To provide surface coverage preventing oxygen loss and evaporation. The pads shade and decaying matter.
Pond Fish (Two Fish approximately 4 to 5 inches in length)
To eat pests such as aphids, flies and mosquito larvae and consume oxygen produced by plants.
