Pond Algae Basics

Pond algae are formed by nature and, generally speaking, are essential for the overall health of the pond. Experts have pointed out the importance of algae, specifically the planktonic varieties, in any body of water. But there comes a point where algae become more of a nuisance than a contributor to the soundness of a pond ecosystem.

Advantages and Disadvantages of Pond Algae

Planktons are the most common type of algae in the world and they provide the biggest benefit. These single-celled algae are considered as a major source of food for aquatic animals, be it in small ponds or in the open ocean. Being an essential part of the food chain, there is no doubt that algae are essential for the maintenance of the pond.  Owners of expensive tropical fish even fertilize their ponds to enhance the growth of planktons.

A healthy level of algae growth in pond can also support the production of oxygen needed by fish and other animals in the pond. That’s why, for some pond owners, the green algae slime that line the edges of the pond is a good indicator that a pond is well-developed.

Nevertheless, pond algae are not without problems. Pond owners know that uncontrolled growth of planktonic and other types of algae causes water to become green, which can prohibit a clear view of the water. Besides, having a green-colored pond certainly looks ugly as it can make the water appear murky like pea soup.

Next, too much algae in the pond can also hamper photosynthesis, a process by which plants transform sunlight and carbon dioxide into food. Since overabundance of algae can prevent the sun from penetrating the water, other types of plants in the pond will have a hard time producing food. Worse, too much algae can also decrease the amount of oxygen in the pond which is very much needed for processes like the breaking down of decomposing organisms. Needless to say, a slowdown in the manufacture of oxygen can have serious consequences for aquatic animals.

Dealing with Too Much Pond Algae

Fortunately, there are many ways to deal with algae overgrowth. The important thing to do is to impede their reproduction and bring back the balance of the ecosystem in the pond. You can use chemical or natural treatment solutions. Even the simple routine of changing about 30% of the pond water every week can do a great job in putting algae production in check. But always remember, algae by themselves are not the problem. Rather, it is the pond owner’s habits and practices that give way to the disadvantages of too much pond algae.
