What are the methods of controlling algae?
Such methods include biological, physical and chemical controls. Biological controls involve introducing species that prey on algae. Physical control such as raking or seining is another option for filamentous or macroalgae, but it is not a viable approach for planktonic algae due to their microscopic nature.
What are the two types of macroalgae?
The two main kinds of macroalgae are Chara or Nitella. These species can be undesirable as a result of their tendency to grow quickly, carpet the bottom of the pond, and crowd out other aquatic plants. If a pond suffers from algal overgrowth problems, there are several possible approaches to controlling algae.
What type of algae is good for ponds?

Of greater concern are blooms that are dominated by blue-green algae (technically cyanobacteria). Unlike many other types of plankton algae, blue-green algae often cause odors, unsightly surface scums (that are not necessarily blue green in color) and, in rare cases, toxins that can injure animals and humans.
Why do plankton bloom?
While plankton algae blooms occur in response to warm and sunny conditions in the summer, the algae growth is supported by high levels of nutrients in the water (most often phosphorus and nitrogen) that may come from fertilizers, manures, septic systems, urban runoff or animal waste entering the pond. Plankton algae provide important benefits ...
Why are plankton algae important to the ecosystem?
Plankton algae provide important benefits to the pond ecosystem. They support the base of the food chain in the pond or lake and are fed on by zooplankton (microscopic animals) which, in turn, become food for fish. Thus, ponds with abundant planktonic algae are often able to support larger populations of fish that grow more quickly.
How to reduce planktonic algae?
Installation of aeration devices may also be beneficial in reducing planktonic algae growth during the summer by mixing different sections of the pond water and by adding oxygen that helps break down old organic matter.
Do plankton blooms kill fish?
Moderate blooms of most plankton algae are generally beneficial and not a concern for the pond ecosystem, but large blooms can sometimes kill fish later in the summer as the algae decompose and remove oxygen from the water. Of greater concern are blooms that are dominated by blue-green algae (technically cyanobacteria).
Algae Explained
Algae does not have a defined root system and often floats on the pond's surface in mats, although it may emerge at the pond's bottom before floating to the surface or even turn the water green. Before treating, it is important to understand the varieties of algae and where they live in an aquatic ecosystem.
Algae Pros and Cons
Surprisingly, algae has many benefits to a pond's ecosystem. The tiny plants feed fish and make great homes for micro- and macro-invertebrates like bugs and worms. But algae has its definite drawbacks. Besides being unsightly and odorous, uncontrolled blooms can cause oxygen depletion, affect fish, and in extreme circumstances, cause fish kills.
When to Treat
The key to successfully treating algae – whether planktonic, filamentous or chara – is to make the most contact between actively growing algae and an algaecide. If the algae is cut or broken into smaller pieces, it's harder for the chemicals to make contact. Because algae do not have a defined root system, it will just keep growing.
Test the Water
Prior to selecting an algaecide, check the water temperature, pH and carbonate hardness. Some algaecides, like Algae Defense, work best when water temperatures are above 60°F. Many algaecides are copper based and should not use with koi, trout, or goldfish unless carbonate hardness (KH) is above 50 ppm.
Proactive Approach
The best way to fight algae and weed growth is to be proactive about pond management. With the use of pond dyes to shade the water, bacteria augmentation and sub-surface aeration, you will be on your way to addressing the root of the problem — excess nutrients and sunlight.

There are seven main types of algae, and they each have their own distinct characteristics. The least common algae species are Xanthophyta (Yellow-green algae). They are single-celled and their cell walls are made up of both silica and cellulose. Paeophyta (Brown algae) are some of the largest species of algae.
How do red algae reproduce?
This type of algae reproduces asexually via mono-spores (spherical, walled cells that do not have flagella). These mono-spores are carried by currents of water until they germinate. Red algae reproduce asexually as well and undergo alternation of generations. Several different types of seaweed are formed by red algae.
Where do yellow green algae live?
Usually, the form into small colonies and have just a couple of cells. Typically, yellow-green algae live in freshwater. However, they can also be found in wet soil and saltwater environments.
Chemical Treatments
If you have an existing algae problem and need to know how to kill algae in a pond quickly, chemical treatments are the way to go. Selecting the best algaecide for your pond will depend on the types of pond algae you are looking to treat. For fine planktonic algae that causes green water, Algae D-Solv or other liquid chemicals are a great option.
