BACKYARD POND #588046 - Ask Extension



Asked August 11, 2019, 12:45 AM EDT

Do the frogs in my pond indicate that I have a healthy pond? I am concerned of blue green algae. I don't think I have a problem. Would the frogs survive in blue green algae is the question. Thank you.

Thank you for using eXtension for your pond question. Blue green algae is a form of cyanobacteria and is considered one of the "Harmful Algal Blooms" that are know to be toxic to animals and fish. they are frequently associated with heavy nutrient loading in a body of water. The result is often water that looks very cloudy and bright green to greenish brown colored.  
Algae, string algae, duckweed and the like are indications of a normal healthy pond. Conversely pea soup colored cloudy water ponds in August are suspect.  
You are correct in presuming that your frogs would vacate such a place.
