Treating Planktonic Algae

Green water or pea soup conditions on your pond got you down?  Mid-summer is a prime time for planktonic algae (otherwise known as green water or pea soup algae) to bloom and turn your water very green. 

First of all, planktonic algae do not form a mat; it simply floats around in the water or on the water’s surface all by its microscopic self.  Many individual plankton cells create the appearance of green water or pea soup.  Planktonic algae are generally used as food by zooplankton, which are then consumed by small fish.  However, some planktonic algae, such as blue-green algae, can be toxic to livestock. 

The obvious interest in planktonic algae is how to prevent it and how to eliminate it.  Prevention is a good way to try to head off a planktonic algae bloom.  High nutrient loads and bright sunlight aid in the growth of planktonic algae.  Use plenty of pond dye such as Crystal Blue, Ocean Blue or Black Out.  Reduce nutrients in your pond by using Natural Pond Cleaner.  Also, the use of an aerator is recommended as it aids in the breakdown of nutrients and in the introduction of air to the water column. 

If it is too late to prevent the bloom, then treatment may be necessary.  Planktonic algae are so small that copper sulfate in its raw form will not be effective.  One must use a chelated copper product such as Crystal Plex in order to eliminate the bloom.  Keep in mind that the sudden death of planktonic algae could cause a fish kill, so use the product responsibly.  All in all, early prevention is the healthiest and easiest method to remedy a pond from the scourge of planktonic algae.
