Pond Algae Control, Pond Water Clarity & Sludge Reduction

Algae is an aquatic organism that is is a naturally occurring and abundant in nature. This complex organism is troublesome to many lakes, ponds, lagoons and wastewater treatment systems.

There are many types of algae and duckweed that cause issues during the warmer months as lakes and ponds go through a "turnover effect." One of the main complaints during this process is the odor. The most common types of algae that cause this odor are filamentous and microscopic.

Algae In Ponds

Why does algae and duckweed grow?

Nitrogen, potassium and phosphorous provide the nutrients algae need to survive in the water. An alga rids closed water of nitrogen build-up caused by aquatic life excretions. Run off from fertilizer only makes this problem worse. It throws the pH off, which also causes blooms. Unhealthy conditions such as these threaten the eco-system organisms such as fish, plants and other aquatic life.

Murky water, lower oxygen levels and less sunlight penetration are often the result of un-monitored duckweed and algae growth.

What can I do to control algae and duckweed growth in my pond or lake?

In order to avoid maintain water quality; prevent sludge and other intruders that pose a threat to aquatic life, it is important to provide the proper environment. We recommend bioaugmentation, a natural and non-chemical means of removing the essential nutrients algae requires to survive. Here is how it works: the microbes take in the carbon, phosphorous and potassium treatment very quickly. This then reduces the amount of nutrients that are available for the algae to consume and thrive off.

When should I start a program to control algae and duckweed in my pond, lake or lagoon?

Colder Climates: It is ideal to start the treatment prior to the "turnover" process, which takes place in early spring. During the "turnover" process, excess organics secrete into a closed body of water. When treatment starts prior to this process, a high concentration of microbes is added. By starting the treatment process before the “turnover” we can establish a high concentration of microbes throughout the water body. It is ideal for water temperatures to be at least 50 degrees F.

Warmer Climates: During warmer months, duckweed and algae treatments can be applied on a year round maintenance schedule.

Benefits of microbes in ponds, lakes, fish ponds and other closed water bodies.

Beneficial bacteria or microbes are very important to your water body. This good bacteria ingests the excess nutrients, which means the algae cannot. This starves the algae and therefore prevents it from growing. This beneficial bacteria has many benefits, such as:

  • Reduction in sludge
  • Improved water clarity
  • Reduced odors
  • Excess nutrient removal
  • Breaks down fish and other organism waste
How much beneficial bacteria do I need to add to my ponds?

Correct dosing instructions are found on both the product labeling and on our product information sheet. General dosing requirements are noted below:

Typical dosing rates (refer to product documentation for more information):

SHOCK DOSE: Apply at a rate of 6-8 lbs. per acre-foot x 5 doses over a two week period. Apply evenly over affected area by dispersing in several areas of the pond, lagoon, etc. MAINTENANCE DOSE: Apply at a rate of 4 lbs. per acre-foot 1-2 times per week dispersing across the surface area of the pond. PREVENTATIVE DOSAGE: Apply at a rate of 2 lbs. per acre-foot, beginning in the spring throughout the warm months. In warmer climates, you can treat ponds and lagoons year round.

If fertilizer is applied to surrounding areas, double the dosage rate for 2 weeks.

Notes: For colder climates Lagoon and Pond treatment program should begin when the water temperature is above 50 Degrees Fahrenheit. In ponds with heavy weed concentration we recommend (if possible) you rake out as many of these dead weeds as you can. By doing this initially to your pond it will increase your ponds recovery time going forward.
