Control Pond Algae for a Clean, Healthy and Beautiful Pond

Share Article

The ability to identify the type of algae in a pond and then to limit the nutrients available to it goes a long way in preventing pond algae growth.

No matter if it is a decorative pond, water garden, golf course pond or stock tank, proper pond maintenance should be on all pond owners’ minds. A first step to proper pond maintenance is to understand one of the largest pests, algae.

There are 3 basic types of pond algae:

Planktonic algae are microscopic, free floating algae the give ponds their clear green color. A normal population of planktonic algae is mandatory for a healthy pond, as they are the base of the food chain and are responsible for supplying the pond with dissolved oxygen, essential for the health of the other aquatic life. When planktonic algae start to bloom, they will give ponds a pea soup coloration. This usually takes place in summer months.

Filamentous algae, often called pond scum or pond moss, begins growing on the bottom of ponds on surfaces like rocks and logs and resemble green fur. As the clumps grow, they break loose from the bottom and float to the top, causing ugly green mats on the pond surface. Filamentous algae begins growing in the early spring and is first noticed around the edges of the pond in shallow water. It has no redeemable value to a pond.

Attached-erect algae commonly are mistaken for a higher vascular plant due to its dense, gritty appearance and its resemblance to aquatic plants with leaf-like structures. Attached-erect algae are less common, but do to its thickness, blooms can be dangerous to swimmers along with being a nuisance to other water activities. Attached-erect algae provide no significant value to a pond system.

Algae blooms in ponds are stimulated by the availability of excess nutrients in the pond and sunlight penetration. Excess nutrients usually come from fish feces, decaying vegetation, fish food and fertilization run-off. Shallow, clear ponds are often the most likely environments for algae to occur, due to the ability of sunlight to penetrate through to the bottom soil.

To safely and effectively control pond algae, the nutrients in a pond should be either removed or prevented from entering. Aerators and fountains that introduce oxygen into the pond will aid in the ability of the pond to quickly breakdown the organic matter, which releases the nutrients. Microorganisms and bacteria can be added to consume excess nutrients and additionally aid in the decomposing of organic matter. Various barriers or prohibitive enclosures can be installed around the pond to limit fertilizer run-off, which is often time a major cause of nutrients. Finally, coloring agents that change the color of the water and limit sunlight penetration are also useful in a pond treatment program.

The market is wide and vast concerning pond treatment options. However the best approach to take to maintain a healthy pond is to be proactive and take preventative measures before a problem can arise.
