KNOW THE BASICS
• The key to creating a natural
aquatic ecosystem is to introduce plants and fish. These elements will not only make the pond look more natural, but will also help to create a diverse ecosystem. The plants help clean and oxygenate the water and the fish keep the tadpoles and mosquito larvae under control.
• When the pool is established
initially, there will be a temporary algal bloom (dark green colour) for about 2-3 months while the plants are settling in and the natural processes are establishing. This will clear up after a short time. When you start to see wrigglers (mosquito larvae) in the water, it’s an indication the water is capable of supporting life, and it’s time to add plants and fish!
• You need to have a diversity
of different aquatic plants in your pond, including fully submerged, floating and marginal species. To accommodate those plants that prefer shallow water, raised platforms can be created from stacked concrete blocks or heavy plant stands.
• Note that pool fencing
laws apply to your pond also – check with your local authorities as to what’s required.
