Algae control

Product Content – Pond Zinger Flocculant/Phosphate Remover – AquaForte

Pond Zinger Flocculant/Phosphate Remover is a powerful and targeted water treatment product specially developed to quickly and effectively remove phosphates and suspended dirt particles from pond water. This targeted approach structurally limits the main nutrient source for algae, resulting in clearer water and a better manageable pond environment.

The flocculating action of Pond Zinger causes fine suspended particles, which normally continue to circulate through the filter system, to clump together into larger particles. These can then easily be mechanically filtered out or settle, quickly improving the visual clarity of the water. At the same time, the product binds phosphates, which are responsible for unwanted algae growth and water pollution.

Pond Zinger is suitable for both ornamental ponds and koi ponds and can be used for acute water problems, seasonal startup, or as part of regular maintenance. The product works correctively and preventively and supports a stable water quality without disrupting the biological balance.

Thanks to the controlled composition, Pond Zinger is safe for fish, plants, and beneficial bacteria, provided it is used according to the guidelines. Its use reduces the need for intensive interventions and increases the efficiency of existing filter systems.

Application Benefits

• Effective phosphate binding

• Rapid reduction of suspended dirt

• Inhibits algae growth at the source

• Improves water clarity and stability

• Supports professional pond management

Pond Zinger Flocculant/Phosphate Remover positions itself as a strategic tool for pond owners who aim for control, clarity, and long-lasting water quality with minimal operational effort.

Use biocidal products carefully. Always read the label and product information before use.

After years of research and countless applications in the fields of erosion and silt control, stormwater treatment, and pond clarification, we are proud to introduce a new product to the pond market: the Pond Zinger™. The Pond Zinger™ is made from safe, non-toxic polymers and has been specially developed to clarify ponds, safely remove algae, and reduce phosphates.

The Pond Zinger™ safely removes algae from ponds, promoting a healthy ecosystem with clean, clear water in which fish and other aquatic life can thrive. The Pond Zinger™ is easy to place near a fountain, air stone, waterfall, or filter. It then slowly dissolves, releasing active ingredients into the water to bind and settle excess nutrients such as phosphorus.

The result is improved water quality in terms of clarity, reduced phosphates and algae, reduced odors, and less suspended solids. The sediment can be further broken down by MicrobeLift Clean & Clear!

Independent studies have shown that Pond Zinger can remove 75–85% of phosphorus from ponds!

Once the pond is clear, any remaining part of the Pond Zinger™ can be removed and stored away from sunlight for later use.

The pond will remain clear for much of the season unless more phosphorus enters the water.

Two versions are available for different water volumes: Pond Zinger: up to 45,000 liters Pond Log: up to 400,000 liters

AquaForte Phospat Filter Cartridge | Powerful Phosphate Removal for Ponds, Swimming Ponds and Fountains

The AquaForte Phospat filter cartridges are the ideal solution for effectively and permanently removing phosphate from pond or fountain water. Phosphate is one of the most important nutrients for (filamentous) algae. By keeping phosphate levels below the critical limit of 0.035 mg/l, algae growth is actively suppressed without negatively affecting plants or beneficial bacteria.

Unlike many other phosphate-binding agents, Phospat cartridges never release the bound phosphate, even when saturated. This makes them a safe, stable and sustainable solution for clear and healthy water. Furthermore, their phosphate-binding capacity is up to 30 times greater than that of traditional iron(III) oxide-based products.

The cartridges consist of three layers of filter media for maximum performance and a stable flow rate. Available in two sizes:

• Phospat 1:

  • Capacity: Up to 90,000 mg of phosphate absorption

  • Flow rate: Max. 1100 l/h

  • Suitable for ponds up to ±50 m³

  • Max. operating pressure: 6 bar

• Phospat 3:

  • Capacity: Up to 270,000 mg of phosphate absorption

  • Flow rate: Max. 3300 l/h

  • Suitable for ponds up to ±150 m³

  • Max. operating pressure: 4 bar

The cartridges are not refillable or regenerable and must be completely replaced once they are saturated. Multiple cartridges can be combined for larger ponds or installations. For optimal performance, the Phospat cartridges should be placed behind a pre-filter to prevent clogging.

Benefits at a glance:

• Effectively reduces phosphate to below 0.035 mg/l

• No re-release of bound phosphate

• Supports the operation of the biofilter

• Safe for plants, fish and bacteria

• Ideal for ponds, swimming ponds, fountains and water features

• Easy to integrate into existing systems

With the AquaForte Phospat cartridges, you are choosing a powerful, reliable and low-maintenance method to keep your pond water free from excessive algae and phosphate for a long time.
