Planktonic algae are microscopic algae that are an important part of the food chain for other micro- and macroorganisms as well as freshly-hatched fish fry. Sometimes, planktonic algae can bloom to nuisance levels which can cause oxygen depletion and fish kills.
Planktonic algae are free floating plants that are suspended in the top layers of the water where they can photosynthesize. They are composed of green algae, blue-green algae, diatoms, and euglenas. Because of this composition, some planktonic algae can be toxic to animals and cause a bad taste and odor in the water.
Planktonic algae blooms are caused by excess nutrients in the water from runoff water sources from septic systems, lawn fertilizers, and goose excrement.
These algae blooms can be treated using Copper Sulfate. Planktonic algae have a high reproductive rate and re-blooms can occur. Because of this, several treatments may be needed throughout the season.
