Most water quality problems in lakes and ponds fall into one of two scenarios — either a sudden bloom or imbalance that needs fast correction, or a slow accumulation of nutrients and sediment that quietly undermines water quality over months and years. Parklink stocks two complementary types of treatment additive to address each: chemical intervention products for immediate knockdown of an active problem, and biological additives that work in the background to keep conditions stable and prevent problems from re-emerging. Used together, they form a complete treatment programme — chemical to reset, biological to maintain.
Fast-acting algaecides, oxidisers and binders for an active problem
Chemical intervention is what you reach for when a water body is already in trouble — a visible algae bloom, a cyanobacteria outbreak, a sudden drop in clarity, or an oxygen crash. These products work fast, often showing visible results within hours of application, and are designed for one-off or infrequent use rather than ongoing dosing. Our range includes broad-spectrum algaecides (REGEN-Alguard and REGEN-Algaemaster), a targeted cyanobacteria oxidiser (REGEN-CyaNo), and a phosphorus binder and flocculant (REGEN-Floc) that locks up dissolved nutrients and drops suspended sediment out of the water column. Applied at the right moment, a single treatment can bring an out-of-control situation back under control in days.
Ongoing maintenance to prevent problems before they start
Biological additives take a different approach. Rather than killing existing algae or chemically binding nutrients, they work with the natural ecosystem — introducing beneficial bacteria and enzymes that consume the organic load, break down sludge, and starve algae of the nutrients they need to bloom. The trade-off is that they work over weeks and months, not hours, so they’re not the right tool for a crisis. They are, however, the most cost-effective way to keep a lake or pond stable once it’s in good condition. Most biological programmes involve regular dosing through the warmer months, scaled to water volume and nutrient load. Learn more about biological additives →
Cyanobacterial blooms are a significant public health issue, particularly in summer Cyanobacteria (blue-green algae) produce a variety of toxins such as hepatotoxins, neurotoxins and dermatoxins which are detrimental to human and animal health.
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.
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-Floc® is a complete water quality and clarity restoration tool. This advanced probiotic and flocculant combine scientific research in bioengineering, phosphorus binding, and coagulation/flocculation resulting in a product that will improve all aspects of water quality. REGEN-Floc® provides a natural way to stop lake eutrophication and restore your lake to a more pristine state.
Eutrophication is when a lake receives excess nutrients (phosphorus and nitrogen) from the watershed and from deposited sediments, called internal nutrient loading. These excess nutrients lead to poor water clarity, algae blooms, low oxygen levels and an imbalanced ecosystem. Nutrients need to be maintained in lower amounts with good water clarity to promote a naturally balanced ecosystem where aquatic life thrives.
REGEN-Floc<sup>®</sup> completely reverses eutrophication by removing excess nutrients and turbidity. This one-of-a-kind proprietary formula of select bacterial cultures, flocculant, and phosphorus binders works in synergy to provide a complete restoration solution that permanently binds phosphorus in water and sediments, reduces nitrogen, and removes unwanted turbidity.
– Breaks down organics and binds phosphorus in the water column
– Improves water quality and clarity within hours
– Eliminates internal phosphorus re-cycling from the sediment
– Safe and easy liquid formulation with no irrigation restrictions
– Does not impact water pH or alkalinity
– Maintains desired turbidity, TSS, and Secchi

Use REGEN-CyaNo® to control Cyanobacteria. REGEN-CyaNo® is a granular algaecide that can be used to spot-treat targeted areas.
Approved for the selective control of cyanobacteria in lakes, ponds, potable water, aquaculture and wastewater, REGEN-CyaNo® active ingredient creates a powerful oxidation reaction that destroys algal cell membranes and chlorophyll, providing immediate algae control.
REGEN-CyaNo® is the ideal choice to keep your lakes, fishing and farm ponds, aquaculture sites, and other private water bodies pleasing to the eye and safe.
Many water bodies are threatened by excessive nutrients entering through lawn and garden run-off, construction sites, wastewater discharges, detergent wastes, septic tank seepage and agricultural run-off. Excessive nutrients support the dynamic growth of cyanobacteria (blue-green algae) and other aquatic algae, interfering with intended water uses and sometimes presenting health hazards to humans and animals.
