Identifying the growth in your pond is the first step to controlling it. Not all growth is necessarily bad. Some types of algae, such as chara, act as filters that keep your pond water clear and clean. In order to control and kill unwanted algae, ponds should be treated with an algaecide several times a season. Our products give you a safe, cost-effective way to maintain algae growth before it takes over your pond.

Tips For Measuring Your Pond
Finding out the size of your pond should be one of the first steps you take prior to pond treatment. Without knowing the size of your pond you will end up wasting valuable time and money. If your aren’t using enough pond chemicals you will notice little to no change in the condition of your pond. If you are using an excessive amount of pond chemicals you will waste money and potentially harm your fish. Use the formulas below to calculate the size of your pond.
Square/ Rectangular (Gallons):
Multiply length x width x average water depth (feet) x 7.5
Example: 8′ x 4′ x 2′ x 7.5′ = 480 gallons
Multiply length x width, then divide by 43,560 (square feet per acre)
Example: 80′ x 140′ / 43,560 = .2571 which is approximately 1/4 surface acre
Multiply diameter x itself x average water depth (feet) x 5.9.
Example: 4′ x 4′ x 2′ x 5.9 = 188 gallons
Multiply circumference x itself and then divide by 547,390.
Example: 520′ x 520′ / 547,390 = .4939 which is approximately 1/2 surface acre
