APS 800 Series Pond Log®

Clarifying Standing Water Bodies

Applied Polymer Systems products harness the power of environmentally friendly materials to solve numerous water quality, erosion, and sediment challenges. Anionic polyacrylamide (PAM) is a polymer flocculant that can be used for a wide variety of erosion, sediment, and stormwater management applications. APS products bind, stabilize, and/or remove commonly problematic particles like sediment (clays, silt), metals, and nutrients to prevent erosion, clear water, and improve BMP performance. APS products are made and packaged in the United States, are drinking water quality (NSF/ANSI Standard 60 Certified), have been extensively toxicity tested by third party laboratories in accordance with EPA standards, and are safe for both terrestrial and aquatic organisms and environments.

Product Overview

The APS 800 Series Pond Log® is a floating flocculant system powered by polyacrylamide (PAM), designed to clarify standing water in ponds and lakes. It works by aggregating fine suspended solids and excess nutrients, improving clarity and reducing downstream impact. Produced in the USA and verified through EPA-compliant toxicity testing, it offers an environmentally responsible solution for sediment-heavy detention systems.

Reduces Turbidity and Inanimate Nutrients

Improves Water Clarity in Ponds and Lakes

Safe for Aquatic Life and Drinking Water Applications

APS 800 Series Pond Log floating in a clear pond, demonstrating effective sediment and nutrient removal.

Primary Applications

  • Ponds adversely affected by high phosphorus concentrations or suspended sediments
  • Ponds affected by fertilizer and stormwater runoff
  • Residential, municipal, decorative, agricultural, and irrigation ponds
  • Ponds with poor clarity and water quality due to phosphorus and suspended contaminants.

Features and Benefits

  • Safe for fish and sensitive aquatic organisms!
  • Remove >95% of turbidity and suspended sediment
  • Remove >90% of total phosphorus
  • Remove >50-60% of dissolved, reactive phosphorus
  • Remove >70% of metals
  • Improve water quality and clarity
  • Reduce environmental risks and meet water quality standards.

Directions for Use

  • Mixing is key! APS 800 Series Pond Logs® should be placed in the flow of water produced by circulation and water features such as fountains, aerators, circulators, waterfalls, etc.
  • Pond Logs® have built in ropes with attachment loops which can be tied to aerators, fountains, rocks, trees, etc.
  • Water must be flowing around the Pond Logs® to facilitate dissolution and dispersion of the log components – Install Pond Logs directly in flow of water
  • As the dissolved Pond Log® components come into contact with phosphorus and other particulate, they will form larger, heavier agglomerations (floc) that will settle out of the water column

Application Rates

  • 1 Pond Log® per 325,000-500,000 gallons of water (recirculating application) OR
  • 1 Pond Log per 50-70 gpm flow (inflow, stream, and flow through application)
  • Replace Pond Logs® once fully dissolved or if new phosphorus or sediment loads are expected
  • Pond Log® lifespan will depend on mixing device but is typically 2-4 weeks Must be used in flowing water. Flocculation cannot occur without mixing

Precautions / Limitations

  • Use only as directed – exceeding suggested application rates will not improve performance
  • If logs are not dissolving or visible results are not seen in 1 week, ensure log is in flow and contact manufacturer
  • APS 800 Series Pond Logs® have been tailored to specific water and soil types and water sample must be tested to ensure effective results. Testing is necessary and is free
  • Consult manufacturer (Applied Polymer Systems) or authorized distributor to confirm proper site specific formulation and dosage prior to use

Frequently Asked Questions

Here are some quick answers to common questions about APS polymers, flocculants, and stormwater testing. For more details, visit our full FAQ page.

General Company and Approach

  • What does Applied Polymer Systems (APS) do?
    APS develops and supports polymer-based solutions for erosion and sediment control during construction.


    🔗 Learn more about APS

  • What makes APS different from other erosion control suppliers?
    APS focuses on testing, technical support, and correct polymer selection rather than one-size-fits-all products.

    🔗 APS technical support approach | Polymer performance testing

  • Who typically works with APS?
    APS works with engineers, contractors, inspectors, and regulators involved in construction-phase stormwater compliance.

    🔗 Industries served
  • What are flocculants?
    Flocculants help fine sediment particles bind together so they can settle and be captured within BMPs (Best Management Practices).


    🔗 Learn more about flocculants

  • Why are flocculants used in construction stormwater management?
    They address fine silts and clays that traditional sediment controls struggle to capture.

    🔗 Fine sediment and turbidity control solutions

  • Do flocculants replace erosion and sediment controls?
    No. Flocculants enhance the performance of BMPs, not replace them. They work best in combination with properly designed and maintained basins, ditches, and inlet protection.

  • What is APAM?
    APAM stands for Anionic Polyacrylamide, a polymer flocculant commonly used in construction stormwater applications.

    🔗 Anionic PAM overview

  • Is all APAM the same?
    No. Molecular weight and charge density vary, affecting how the polymer interacts with different soils.

    🔗 Polymer selection and matching
  • Why does the charge of a flocculant matter?
    Polymer charge affects how it interacts with sediments and aquatic life.

    🔗 Polymer chemistry and performance

  • Why is anionic PAM preferred for stormwater applications?
    Anionic PAM carries a negative charge that does not readily bind to fish gills or aquatic organisms when used correctly.

    🔗 Environmental considerations for polymer use

  • Why are cationic polymers not used in construction stormwater?
    Cationic polymers carry a positive charge and can bind strongly to fish gills, making them unsafe for stormwater applications.

    🔗 Proper polymer selection guidance

  • How does APAM reduce risk to aquatic life?

    When properly tested and applied, APAM binds fine sediment particles together so they settle and can be captured within BMPs, reducing turbidity and minimizing interaction with aquatic organisms downstream.
