How To Control Planktonic Algaeplanktonic algae

Algae is a uninvited addition to many ponds and lakes but there is one type of algae that can be particularly annoying: planktonic algae. Planktonic algae are so microscopic and can become so plentiful in a body of water that they can turn the water from clear or blue to a yucky green pea soup color. Planktonic algae ruins recreational activities and can ugly up a pond or lake if left untreated for a long period of time. When planktonic algae makes water look like that, who would want to swim in it?

Planktonic algae are floating microscope plants that are actually are a normal inhabitant of sunlit surface waters. In fact they are such an essential part of the aquatic ecosystem that it is pretty much inevitable that you will deal with this issue on your water property. Wherever they are established, there are literally millions of floating planktonic algae, so much so that they color pond water because of their concentration into shades of green, blue-green, brown or variations in between. This occurrence is known as a “bloom” or “algae bloom”. Many species of planktonic algae are involved in algae blooms and these species change over time based on temperature, light, nutrients, and other factors.

As unsightly as they appear, planktonic algae blooms are considered desirable as the beginning of the pond food chain and promote and attract fish populations which like to consume the algae. However, too much planktonic algae can cause oxygen depletions and kill fish as a result.

If you have a problem on your pond or lake with planktonic algae, Solutions Pest & Lawn can provide you with the right products and know-how to successfully remove this unsightly growth from your body of water.

How To Get Rid of Planktonic Algae: 3 Step Solution

Planktonic algae can be a difficult things to manage. What it will take to eliminate it from a body of water completely will need to involve a mixture of both chemical application as well as changing the condition of your pond or lack. This is because large blooms of planktonic algae typically grow because of excessive nutrients in the water. Working to reduce or redirect the nutrients from the pond or lake will help to reduce the algae growth. Here are the steps we recommend if you are looking to tackle this issue the DIY way.

Step 1: First and foremost, a thorough analysis of the body of water where the plantonic algae is present must be done. Using chemicals to treat your pond or lake can be risky so you must consider all the variables like pond size, the ecosystem, the aquatic life in the water that you want to have around like vegetation and fishes etc. One thing that is tough about this algae is that when using an algaecide to control the outbreak, the dead planktonic algae it will deplete oxygen from the water, possibly causing a fish kill if the oxygen depletion is great enough. This is why we suggest a mixture of both organic control methods and pond modification to aid in removing the algae.

Step 2: Once you have selected the best algaecide for you to use, you will then need to determine the application rate as well as time your application at the right time and temperature in order to successfully eliminate planktonic algae.  Applications should begin when algae first appears as long as your water temperatures are above 60°F.  When applying herbicides you should also make sure you have on the proper safety equipment such as protective eyewear, gloves and long sleeve clothing to protect you from possibly coming in contact with chemicals.

Step 3: Apply the chemical treatment to the water using a backpack sprayer or hand-pump sprayer. Exercise precaution and treat your pond in sections to prevent the chemical from harming other life in the water. Treat only half the pond's surface at a time. During hot weather or when treating heavy growth, it is important to treat no more than ¼ of your pond at a time and wait the full 14 days before re-applying. We want to emphasize that unless something is done to reduce the nutrient richness in the water, this algae will continue to be a returning problem.
