Calcium Carbonate

We are a reputable distributor of various Calcium Carbonate products to suit your needs and budget.

Applying Calcium Carbonate is most commonly used as a management technique to reduce organic matter, also known as “Silt”. 

Siltation can pose a risk to all waterbodies and often, if not managed, can lead to loss of amenity.


See below for further benefits of applying Calcium Carbonate to your water.

Neutralisaton of Acidity: Calcium carbonate helps to neutralise acidic conditions in the water, raising the pH to a more neutral or slightly alkaline range (6.5 to 8.5). This is crucial for creating a suitable environment for fish and other aquatic organisms.

Enhanced Water Chemistry: By raising the alkalinity, calcium carbonate helps maintain a stable chemical environment, which supports the health of fish and other aquatic organisms. Higher alkalinity also contributes to more consistent and favourable conditions for fish reproduction and growth.

  • Healthier Fish: Increased water hardness, resulting from higher calcium concentrations, is beneficial for fish. It supports stronger bones and scales, improves osmoregulation (the ability of fish to regulate the balance of salts and water in their bodies).
  • Reduced Toxicity of Metals and Ammonia: Harder water is less susceptible to toxic spikes of ammonia and metals such as copper. Calcium ions in the water help to precipitate toxic substances, making them less available to fish and reducing the risk of poisoning.
  • Support for Phytoplankton Growth: Calcium carbonate can help release bound phosphorus from sediments, making it available for phytoplankton growth. Phytoplankton forms the base of the aquatic food web, supporting zooplankton and other organisms within the aquatic food-chain.
  • Improved Productivity: By promoting the growth of primary producers (like phytoplankton), calcium carbonate enhances the overall productivity of the lake, leading to a healthier fish population.
  • Reduction of Sediment: The introduction of calcium carbonate can help to stabilise sediments at the bottom of the lake, reducing the likelihood of resuspension of fine particles into the water column. This leads to clearer water, and in time, a reduction in organic matter.
  • Enhanced Soil Structure: Calcium carbonate improves the sediment structure, making it more conducive to the growth of aquatic plants. These plants provide habitat and food for fish, further enriching the lake’s ecosystem.

Optimal Growth Conditions: The overall improvement in water chemistry, nutrient availability, and habitat quality creates optimal conditions for fish growth and reproduction. Fish are less stressed, more resilient to disease, and likely to grow larger and healthier in a well-maintained environment.

Affordable and Widely Available: Calcium carbonate is a relatively inexpensive and readily available material. Its application is a cost-effective method for managing water quality and promoting a productivity in aquatic environments
