Pond restoration

Effective Microorganisms (EM) offer an environmentally friendly solution for enhancing water quality. They effectively combat and significantly reduce algae growth and opacities.

The utilization of EM in water systems facilitates the restoration of polluted ecosystems. These microorganisms play a crucial role in reducing nutrient excess, a primary cause of issues like excessive algae blooms. EM comprises beneficial microorganisms commonly found in soil, including yeasts, photosynthetic bacteria, and lactic acid bacteria. The balanced presence of these effective microorganisms supports the overall ecosystem health.

EM works to decompose organic matter, such as leaves, algae, pollen, and fish feed, preventing their accumulation as sediment at the bottom of water bodies. This process leads to faster nutrient dissipation and promotes optimal nutrient levels, facilitating the controlled growth of aquatic plants and phytoplankton, the microalgae. This controlled growth, in turn, supports the proliferation of zooplankton, such as daphnia and crustaceans, which serve as essential food sources for various aquatic organisms.

By establishing a balanced and stable ecological cycle, EM contributes significantly to the development and maintenance of healthy aquatic environments.

Aegir Seashell Grit

Enhancing the microbiome of pond ecosystems is essential for maintaining ecological balance and promoting the health of aquatic organisms. One effective method of achieving this is through the use of Aegir seashell grit, a natural product derived from marine shells. Aegir seashell grit offers unique benefits that support microbial activity and improve overall water quality in ponds.

  • Aegir seashell grit acts as a natural buffer, stabilizing pH levels in pond water and creating an optimal environment for beneficial microorganisms to thrive.

  • The minerals and trace elements present in Aegir seashell grit provide essential nutrients that support the growth of beneficial microbes, aquatic plants, and animals within the pond ecosystem.

  • The physical structure of Aegir seashell grit provides a substrate for biofilm formation, which serves as a habitat for diverse microbial communities. These biofilms act as natural filters, trapping organic matter and excess nutrients, thereby improving water clarity and reducing algae growth.

  • By enhancing water quality and promoting microbial activity, Aegir seashell grit helps to improve water clarity and oxygenation, creating a more hospitable environment for fish and other aquatic organisms.

  • Incorporating Aegir seashell grit into pond management practices offers a natural and sustainable solution for maintaining balance and resilience within pond ecosystems, reducing the need for chemical additives and interventions.

  • 1 kg Ægir Seashell Lime per 1 m2.

EM Pond Clear Boost


EM Pond represents a specialized blend tailored for garden and swimming ponds, comprising a unique assortment of phototrophic bacteria. These bacteria play a crucial role in sustaining optimal water equilibrium within the pond environment. Leveraging the power of light, these bacteria efficiently convert organic substances, ensuring the purity and vitality of pond water, promoting cleanliness and overall pond health..

  • Frequent algae issues in ponds typically signal an abundance of nutrients, particularly nitrogen, fostering the rapid proliferation of algae. This nutrient surplus often stems from overfeeding fish, with over 75% of their ingested food being excreted. As undigested food settles to the pond bottom, it initiates a decomposition process leading to acidification, ultimately fueling algae growth.

  • It is recommended to combine EM Pond clear boost with EM mud balls and pond clear for optimal results.

    Use half a litre of EM Pond boost and 1 litre of pond clear (undiluted) per 10 m3 of pond water.

  • Evenly distribute the EM Pond across the pond's surface using a watering can. The microorganisms within the product face challenges in moving through the water, hence manual dispersion is crucial for their spread and establishment throughout the pond.

  • If the algae growth in your pond or swimming pond becomes excessive and can no longer be adequately treated with pond clear alone, the use of EM Pond booster is recommended.

Establish or restore a biological balance in the water

Pond Clear offers a solution to establish or restore biological balance in your water point, improving quality while ensuring biodegradability and safety.


  • Harness the Power of Effective Micro-organisms in pond clear

    Unlock the potential of pond clears effective Micro-organisms to transform organic matter into vital nutrients, keeping your pond clean and vibrant.

  • Bid farewell to ammonia and nitrites that threaten fish health! Actiferm supplementation accelerates their neutralization, promoting a thriving aquatic environment.

  • Achieve optimal microbial balance with ease using Pond clear. Just apply 10 liters per 10 cubic meters of water litresly for a pond that thrives year-round.

EM mudballs


Maintaining the health and clarity of your pond or natural pool is crucial for creating a vibrant aquatic ecosystem. To combat significant siltation and preserve the natural beauty of your water feature, consider utilizing EM Bokashi Pond Balls. Infused with a potent blend of fermented clay, Bokashi, molasses, and EM Ceramics powder, these balls introduce a diverse array of Effective Microorganisms into the water, offering a natural and sustainable solution to siltation issues.

  • Combat significant siltation in your water point or prevent it altogether with EM Bokashi Pond Balls. Infused with a blend of fermented clay, Bokashi, molasses, and EM Ceramics powder, these balls introduce a multitude of Effective Microorganisms into the water.

  • Watch as the microbial action of EM Bokashi Pond Balls consumes and visibly reduces slime buildup, providing a lasting solution to siltation issues.

  • Apply 1 to 2 balls per square meter of surface annually, adjusting as needed based on the level of mud present. For best results, administer during winter months.
