How To Calculate Treatment Area

 

Surface Acre: L x W
                        43560

Acre Feet:  Multiply Surface Acre by average depth.

Algaecides
 

Algae is single cell plant.  Algaecides must come in contact with each cell. Larger mats should be broken up prior to treatment.  Algaecides work best on bright sunny mornings.  Do not use them if it is overcast or rain is predicted for that day.  Water temperature has to be at least 60 degrees for algaecides to be effective. Treat for algae beyond the trouble area.  New algae forms at the bottom.  By treating beyond the trouble area, you will kill the algae you can not see yet.

Filmentous Algae

 

Not beneficial.  Also known as "pound scum" or "moss" because it forms greenish mats upon the water's surface.  The texture may be slimy, cottony or coarse.  Several total or spot treatments may be required.  Use Cutrine Plus Liquid starting in early May.

Planktonic Algae  

Not beneficial.  Water appears pea soup green or brownish.  Usually suspended in the upper few feet of water. Use Cutrine Plus Liquid.

Attached-Erect
(Chara & Nitella)
 

Beneficial.  This algae is weed like.  Best way to identify it is by its musky odor and gritty, bristly feel.  This algae helps to stabilize bottom sediments, provide good fish habitat, and crowd out less desirable plants.  Use Cutrine Plus Granular.

Resistant Algae  

Jelly like, S.O.S. pads, thick and coarse.  Use Cutrine Plus Liquid with Cide Kick II.
