Filamentous Algae Can Disrupt Pond Use

Welcome rains have filled many depleted ponds. The runoff likely introduced increased nutrients.  The combination of such events this time of year can create optimum conditions for dreaded “filamentous algae”.  We should know by the end of March.

Filamentous is among first plants to appear in spring.  It thrives in 55-75 degree water temps.  Activity is contingent on nutrient levels. Algae grows on bushes or rocks in shallow areas.  At the end of a growth cycle, remnants float to the surface and form large mats that drift around the pond with prevailing winds.  It has a scummy, slimy texture that prompted its common name, “angel hair” algae.  Pesky growth fouls fishing lures and clogs intake lines for irrigation systems.

Mechanical management techniques include dragging clumps out on the shore.  This method is not very effective since remaining plant fragments can stimulate new growth.

Chemical treatments produce fast results.  Copper based products work best. We strongly recommend contacting us before applying chemicals.  Treating too large an area at one time can cause oxygen stress.  State environmental authorities are proposing new regulations that may require permits to treat vegetation in your pond. We’ll relay policies as they develop.  Meanwhile, tilapia are a popular biological method to manage algae.  Stock them at 15 to 20 pounds per surface acre.  Place your order now before supplies dwindle!

Our most successful management plan incorporates aeration, microbes, and tilapia.  Benefits of this program pay big dividends.  Call for details.  You’ll learn fascinating facts about your pond.
