Pithophora

Pithophora is a type of filamentous algae that thrives in shallow ponds high in nitrogen and phosphorus.  It is bright green or brown in color and can form dense mats at the surface of the pond. It can be one of the most difficult types of algae to control.  In heavy wind or rain, the algal mats will sink to the bottom and then float back to the top.  Pithophora floats by trapping air bubbles at the surface where it forms tangled clumps that resemble cotton or wool.  This algae can be treated with a diquat herbicide, applied at a rate of 1-2 gallons per surface acre.

  1. I have got this type of algae a month before in my backyard pond. I have used algaecide to remove it but it was in small amount. I like this information and found very useful. Like it!!
