Algae Wizard - Step 1 of 3

First, Let's Determine Your Pond Size

Use the table below to determine the approximate size of your pond.  This will determine how much product you will need to effectively control your algae problem.  Find the closest length of your pond in the top row, and the closest width of your pond in the left column.  Where the corresponding row and column intersect, you will find the approximate surface area of your pond in acres.  Then Continue to the Algae Identifier

[Length (ft.) x Width (ft.)] / 40,000 = Surface Area (acres)

Optional:

To calculate Acre feet, which is a volumetric measurement, multiply the Surface Area you just calculated by the average depth of your pond, in feet.  This measurement will help you determine dosage.
