Pond Boss Forums INTRO Common Pond Q&A (archives) Filamentous Algae, aka Pond Scum/Moss - Management

Pithophora which is a coarse haired filamentous algae common is southern states can be killed with a combination of Reward and copper sulfate as described by Greg Grimes:
"Mix of liquid copper sulfate and reward will kill it just fine. Might have to treat twice to eradicate. If you want high fish production I suggest not using dye." Also see Greg's alternative suggestion for chemical control second post below.

However as we will see this chemical combination is best used in water with lower alkalinities. For Pithophora that grows in harder water or limestone based soils, see the next post by ewest for Pithophors control recomendations by Ohio State Univ.
