Commercial Lake Management & Restoration


Bio-remediation is defined as any process that uses microorganisms (bacteria) and their enzymes to return a natural environment altered by contaminants to its original condition. Bio-Remediation is a natural process used to reduce, sequester, or eliminate:

  • Suspended organic matter.
  • Soluble inorganic compounds like nitrates.
  • Settled organic solids and organic sludge.

Parklink’s products contain natural bacteria and enzymes to effectively hydrolyse and digest sludge from the bottom of the lake, compete with pond algae for their food source and improve water clarity. The bacteria in the Parklink products are listed as Biosafety Level 1 (non- pathogenic), 100% natural and are not genetically modified.

Note: Clensaqua digests organic sludge (leaves, dead algae, fish waste, etc.). Clensaqua does not digest clay, sand or silt.

Parklink unequivocally state that none of our ingredients are toxic in any way to algae, or to any life form. All of our bacteria are present to some extent in any aquatic system. We simply add more of these bacteria to stimulate the biology enhancing its ability to compete with algae for nutrients and degrade organic solids.

The results of use of our products in an aquatic system include:

  • Establishment of a healthy balance between bacteria and algae
  • Reduced organic solids/sludge accumulations
  • Reduced odour caused by excess organic sludge
  • Improved water clarity


Contamination of water bodies in public parks and reserves is often caused by a lack of aeration, water flow and a build-up of nutrients. This combination becomes too much for the natural ecosystem to handle, resulting in issues with algae, clarity, weed, odour and water quality.

Many lake owners assume that the presence of any algae in their pond is a cause for concern. While it is true that algae growth can easily ruin the appearance, it also has many benefits.

For example, algae provides fish with a healthy food and source of oxygen.  The goal should not be to eliminate all algae. Instead, it should be to manage its growth to keep the population at a desirable level. Knowing what factors contribute to algae growth, and your control options, will help you keep a healthy, well-balanced lake or pond.

Algae blooms and pest weeds can become excessive and as they die and settle to the bottom they provide an additional source of nutrients to support further growth, compounding the problem.  Grass clippings, leaves, manure, fertiliser runoff and rubbish also contribute to this imbalance.

Parklink’s remedial treatment programmes bio-degrade this material effectively and safely with zero harm to wildlife or the natural ecosystem.  The treatment also rapidly reduces the nutrients in the water competing with the algae and weed for their food.  As the nutrients are depleted, algae and weed are controlled naturally without using harmful algaecides or weed sprays.

Parklink have successfully removed huge amounts of contaminated material from lakes and large ponds without the need for mechanical equipment, weed choppers or chemical sprays.

Resource Management Act

Under the Resource Management Act 1991, Councils are required to prepare a district plan “To promote the sustainable management of natural and physical resources.” This can be achieved by ensuring that the waterways are managed in a manner which retains amenity, ecological and natural values.

Our programmed approach promotes the natural character of waterways in preference to artificial pond algae solutions such as cleaning waterways via manual extraction and or chemical processes or continuous and intrusive power consuming treatments.

Parklink’s remedial treatment programmes for lake cleaning will bio-degrade sludge effectively and safely with zero harm to wildlife or the natural ecosystem living in the water.

“I look after the water remediation programme and I have to say what a dramatic improvement, the clarity of the water has improved amazingly!”

“The Kune Kune wallows are now just muddy water which is the look a wallow should be. The sunbear moat has cleared up remarkably and has a clear visible sight line of 700mm deep with a slightly muddy appearance under that. The algae coverage has dropped amazingly on the waterfall. The tiger pond is clear as with a slight layer of algae on the molded shape.”

“The 2 lagoons, both gibbon and monkey island which were both duck weed infested murky zika infested things, have probably made the most startling transformation of the lot. With most of the duck weed gone and both remarkably clear as much as to say ‘man I can see all the crap on the bottom now’. They at times appear muddyish but then also at times look really clear, quite amazing to turn up early in the morning to see the ponds calm as and slightly bubbling as the process works.”

“The otter ponds both just look like fresh running water when you look over the fence into both habitats, there is a little layer of algae on the viewing window but a way lot better than it was.”
