Pond Science 101:
A pond is basically an earthen basin lined with a material that prevents the seepage of water. This type of aquatic ecosystem is full of animals and plants who interact and depend upon each other until some of them get too much food. Now is when conditions change.
Excess nutrients like nitrate or phosphorus can become available from within the pond or enter from external sources and are rapidly consumed by simpler micro-sized organisms causing autotrophic biomass like blooms. At this point you may become concerned about the health of your pond and seek a form of remediation. The choices are biological, chemical, or mechanical.
Mechanical remediation is a viable option for removing a thick layer of organic sediments (black muck) from a fully mature pond but will do little to improve nutrient cycling. Have you tried raking duckweed or algae? No fun.
Chemical remediation involves the application of chemicals which seldom process excess nutrients but rather control or kill the aquatic organisms that grow in response to the nutrient. Sometimes it is the only option especially when dealing with invasive species. We view this form of remediation as quick but short termed.
What’s left is biological remediation, a natural approach which is available in different strategies and degrees of effectiveness. Dissolved nitrate and phosphorus are the primary nutrients which need to be minimized for balanced aquatic plant and animal growth. Nitrate levels below 10ppm and phosphorus levels below 1.0ppm are ideal for a healthy pond.
Establishing beds of aquatic plants along the edge of a pond, floating wetlands, and phyto filtration are natural strategies for removing nutrients that support green algae and duckweed growth. As bacteria cells colonize on the roots of these plants, the efficiency is improved until cold weather reduces the plant growth. When these plants expire and decay some nutrients are released back into the pond.
Natural bacteria (beneficial) already exist in most freshwater ponds as heterotrophic, nitrifying, and photosynthesizing. Commercially prepared bacterial products are sold in liquid and powder form and are used to supplement the existing cultures living in the pond. Sometimes aeration is needed to assist the bio augmentation process. The strategy of using bacteria depends on product selection, application, water temperature and acceptable PH levels.
Installing a Country Pond filter with micro algae is a new biological option for pond owners. All aquatic organisms practice competitive exclusion to some degree and it just happens that some are better at out competing others for nitrate or phosphorus. This filter supports the growth of micro algae that is non-toxic, found worldwide, and is less affected by temperature than plants or bacteria.
Adding fish to your pond or water garden can increase the enjoyment of your pond. Watching koi and goldfish gracefully swim around your water garden is a very relaxing experience.
Japanese Koi and goldfish are not recommended for natural bodies of water. Japanese koi, domestic koi and goldfish are generally available from March through November. Because no two koi are exactly alike their are considered to be swimming works of art.
