Cleaning your pond naturally with beneficial micro-organisms

Natural water quality improvement is largely dependent on teams of beneficial micro-organisms. One group starts a process, which is continued by others. It has been shown in scientific research that, even in natural lakes, essential members of these microbial teams are not always present.

Micro-organisms present in pond bacteria help control water qualityTime, location and the seasons will affect your pond often resulting in bad smells and muck build-up. This is the natural aging process which, if left unchecked will rapidly deteriorate the quality of your pond or lake. Adding safe and natural bacteria which feeds on organic matter will drastically improve your pond.

There are two kinds of aquatic pollution: insoluble and soluble. Lakes accumulate solids from dead plants and animal wastes. Soluble pollutants, from fertilizers, erosion and seepage, add phosphorus and nitrogen – nutrients for algae and weeds. The plants convert, by photosynthesis, inorganic carbon dioxide into organic material. Dead plants form organic sludge, the accumulation of which results in oxygen depletion and release of noxious pollutants such as ammonia and hydrogen sulphide. Phosphorus is also liberated for reuse by plants. Oxygen can be reduced to levels causing fish kills. The stress caused by poor water quality also reduces fish growth and makes them more susceptible to diseases.

One very common aquatic weed problem in ponds is filamentous algae. The presence can degrade water quality and the enjoyment and value of your pond. Excessive algae growth, if left unchecked can cause oxygen depletion as it decomposes either as a result of natural die-off, herbicide or fertilizer applications. Early and regular control is important to reduce the problems like muck and foul odours associated with filamentous algae.

Filamentous algae, also known as “pond scum,” forms dense hair like strands that can form thick floating mats. Its growth begins on submerged objects on the pond bottom. As it grows, the algae give off oxygen that becomes entrapped in the mat of strands. This gives it buoyancy and causes it to rise to the surface where it frequently covers large areas of the pond. Filamentous algae are often a persistent problem because they reproduce by fragments, spores and cell division. Treatment with beneficial bacteria can solve this problem.
