Filamentous algae can spread within days and cause severe damage.



Napier Wild Life Reserve

Napier City Council

The density of Algae had reached a point that large swans were only able to make their way through it by flapping and crawling over the top. The algae had grown in the deeper zones in massive column type structures that were over 1.8 meters tall

Napier City Council had exhausted all avenues to help fix the situation but seemed resigned to the fact that mechanical extraction was the only feasible way to keep the algae back.
The council was approached by the Parklink Bioremediation consultants and the suggestion of using a biological process to clean up the water way was put to them. After a thorough investigation of all factors, surroundings and water qualities a plan was put together to start a treatment process that was to run for a minimum of 2-3 years. The council accepted the proposal and work began at the end of June 2002.

REGEN-Algaemaster®

REGEN-Algaemaster®

The powerful oxidation of REGEN-Algaemaster® Granular Algaecide breaks down algae cells on contact – you can see it working! Its unique organic chemistry immediately begins fighting algae blooms and releasing vital oxygen into the water as it biodegrades. It can be used as a curative or preventative treatment in any water body, including those that contain fish, plants, and other aquatic life. Formulated without using harsh chemicals, you can be sure there won’t be any negative effects on the aquatic ecosystem.

REGEN-Algaemaster® Algaecide is effective and offers immediate results when eliminating algae. With an environmentally sound chemistry that is chlorine, copper, and phosphate-free you can confidently use Parklink’s Granular Algaecide in water features without circulation systems. For best results, apply in the morning hours of a calm sunny day when water temperatures are warm. Sunlight and higher temperatures will enhance REGEN-Algaemaster® Algaecide activity.

Where, when and how to use

REGEN-Algaemaster® Granular Algaecide can be used with confidence in lakes, ponds, ornamental ponds, fountains, irrigation ponds, farm dams and other water features.

It is recommended to use this product at the first sign of algae growth. For best results, apply in the morning hours when the water is warm; sunlight and higher water temperatures accelerate REGEN-Algaemaster® Granular’s activity.

Check the water’s pH levels before application; the pH should be between 6.8-7.8. Turn off any water circulation for 10-20 minutes when applying. Administer to affected areas and skim dead algae from the water’s surface to prevent future growth.

Why REGEN-Algaemaster®?

REGEN-Algaemaster® Granular Algaecide uses its unique and powerful chemistry to control algae blooms. Through the power of oxidation, its effects can be seen after a few minutes. Formulated without the use of harsh chemicals, REGEN-Algaemaster® Granular Algaecide leaves no chemical residual and benefits the aquatic ecosystem by releasing vital oxygen into the water as it biodegrades.

REGEN-Alguard

REGEN-Alguard

REGEN-Alguard® is a commercial-grade liquid chelated copper-based algaecide, used for the safe, rapid and effective control of a broad spectrum of filamentous and planktonic algae.  REGEN-Alguard® is up to 80% less copper than current (copper-based) algaecides and is widely used to control algae in lakes, irrigation dams, decorative ponds and more.  REGEN-Alguard® will not harm fish, livestock, plants, pastures or turf (when used in accordance with label instructions).

REGEN-Alguard® works by weakening cyanobacteria and algae cells. Copper ions stop photosynthesis causing the cells to die and dissolve into the water.  There is minimal harm to organisms in the water.  Residual toxins are rapidly biodegraded.  REGEN-Alguard® rapidly disperses throughout the water body without settling to the bottom or floating on top like other copper-based algaecides.

How to Use

Apply in a manner that will ensure even product distribution within the treatment area. Retreat areas if regrowth begins to appear or if seasonal control is desired. Repeating application of this product too soon after initial application may have no effect. Treatment of aquatic weeds and algae can result in oxygen loss from the decomposition of dead biomass. This oxygen loss can cause fish and invertebrate suffocation. To minimize this hazard, do not treat more than ½ of the water body and wait at least 14 days between treatments to avoid depletion of oxygen.  Begin treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas. Application of algaecides to high-density blooms of cyanobacteria can result in the release of intracellular contents into the water. Some of these intracellular compounds are known mammalian hepato- and nervous system toxins. Therefore, to minimize the risk of toxin leakage, manage cyanobacteria effectively in order to avoid applying this product when blooms of toxin-producing cyanobacteria are present at high density. Certain water conditions including low pH (≤6.5), low dissolved organic carbon (DOC) levels (3.0 mg/L or lower) and “soft” waters (i.e. alkalinity less than 50 mg/L) increases the potential acute toxicity to non-target aquatic organisms. The application rates on the label are appropriate for water with pH values > 6.5, DOC levels >3.0 mg/L, and alkalinity greater than 50 mg/L. Avoid treating waters with pH values <6.5, DOC levels <3.0 and alkalinity less than 50ppm (e.g., soft or acid water), as koi, trout and other sensitive species of fish may be killed under such conditions.

REGEN-Enhancer®

REGEN-Enhancer®

Improve the effectiveness of algaecides and herbicides

REGEN-Enhancer® is a natural catalyst that accelerates chemical treatments by improving penetration.  When mixed with an algaecide or herbicide it speeds the breakdown of dead algae and aquatic plants while stimulating naturally occurring bacteria to fixate nutrients liberated during this process. This complex blend of enzymes, cultures, fungi, and stimulants dissolves the dead algae and aquatic plants on a cellular level, reducing their contribution of nutrients.

By accelerating chemical reactions, REGEN-Enhancer® improves copper algaecide performance. This is especially critical in hard water applications when copper solubility and performance is reduced.

REGEN-Enhancer® alone does not kill anything.

See how it works

The science behind it

The cells of algae and aquatic plants can be thought of as a series of well-engineered structures. These structures are made of complex proteins, carbohydrates, lipids, and minerals. Chlorophyll is stored within the chloroplasts in the cell, and chlorophyll is how a plant gets it energy to grow from sunlight. This intricate framework allows algae and aquatic plants to grow and thrive while aiding in resistance to chemical treatments.

Improving the performance of contact algaecides and aquatic herbicides

Contact algaecides (copper products, peroxides, and herbicides) must contact the cell wall and enter the cell to be effective.  The lack of penetration and intercellular movement of these chemistries reduces their effectiveness.  REGEN-Enhancer® degrades dead plant cell walls and weakens cellular integrity when used with an algaecide formulation.  Killing all susceptible cells reduces the risk of algae developing any resistance to chemical treatments.

Improving the performance of systemic herbicides

Systemic herbicides (i.e. glyphosate, imazapyr, or triclopyr) travel through the cell disrupting processes such as amino acid synthesis, cell division, and photosynthesis. Systemic herbicides tend to work slower, but they do translocate into multiple parts of the plant. However, herbicide resistance has been studied in detail and can reduce overall treatment performance and consistency.  For this reason, we focus on a complete degradation of the dead plant structure and aquatic herbicide dispersion to all susceptible cells.

When combined with systemic herbicides, REGEN-Enhancer® speeds movement into the cells by breaking down the cellular framework of dead cells, promoting rapid nutrient recovery, and decomposing dead plant material from the inside out. REGEN-Enhancer® works synergistically with systemic herbicides and ensures thorough and complete degradation of dead aquatic plants.

NOTE: REGEN-Enhancer® DOES NOT kill aquatic plants or algae.

See how it works

The Science Behind It

Water bodies have stress from both external and internal sources. Excessive rains or draught combined with the ongoing use of algaecides and herbicides deplete the microbial communities that are fundamental to nutrient removal in water bodies. This imbalance in the ecosystem leads to elevated nutrient issues and can result in excessive aquatic plant growth, continuing algal blooms, and HAB’s (Harmful Algal Blooms).

REGEN-Balance® was formulated through years of research by obtaining samples from lakes and ponds across the Globe when water temperatures were mild. The natural microbial communities in the samples were analyzed to understand population densities and the specific organisms that are depleted by stresses. This research is how Parklink was able to create a probiotic that supplements natural populations and supports indigenous organisms that are functional and native to that geography. REGEN-Balance® is more than simple additions of beneficial bacteria. It is a scientifically formulated probiotic that works in harmony with the microbial communities that play key roles in nitrogen and phosphorus uptake. Real science. Real Results.
