Sustainable aquaculture farming

A safe & environmentally friendly water conditioner for aquaculture.

About AQUA-Cal+

AQUA-Cal+ is a non-toxic, non-corrosive, safe and environmentally friendly water conditioner for aquaculture.

It stabilises alkalinity, suppresses extreme changes in pH and provides ingestible essential magnesium and calcium. As a result, phytoplankton productivity is improved and toxic metals in the system (such as copper and zinc) along with ammonia and nitrite levels are significantly reduced.

Utilising Calix’s platform technology, AQUA-Cal+ is made by flash calcining a mixture of magnesite and dolomite.

This produces a unique, high surface area powder, which is hydrated to produce a slurry for ease of application to ponds. AQUA-Cal+ has been specially formulated to impact on both the aqueous and benthic ecosystems in the pond.

The opportunity

Aquaculture is one of the fastest growing food-producing sectors in the world.

Yet, productivity is already highly stressed by excessive fishing pressure, organic pollution, toxic contamination, coastal degradation and climate change.

Aquaculture farmers can benefit from more sustainable solutions that efficiently break down polluting sludges, while increasing yields through lower disease and higher feed product efficiencies.

Our solution

AQUA-Cal+ is a non-toxic, non-corrosive, safe and environmentally friendly water conditioner for aquaculture.

The data consistently shows that AQUA-Cal+ stabilises alkalinity; suppresses extreme changes in pH; provides ingestible essential magnesium and calcium; reduces turbidity; improves light penetration; improves phytoplankton productivity; reduces toxic metals in the system (including copper and zinc); and reduces ammonia and nitrite.

Key features & benefits

Improved water quality

AQUA-Cal+ works as a water and pond bottom conditioner, clarifying the water, controlling pH and releasing alkalinity, as required, to aid in the digestion of organic matter.

Less stress on prawn & shrimp

With stabilised conditions in the pond, stress is reduced. When stress is reduced and water conditions are improved, both fish and prawns become healthier and more productive.

Prawn mortality reduced

Conditioning with AQUA-Cal+ removes the iron by flocculation from the water. The turbidity and toxicity are significantly reduced as a result, decreasing the subsequent mortality of the prawns. Stocking of the pond after the water is conditioned reduces the subsequent mortality of the post-larvae.

Sludge volume reduced

As AQUA-Cal+ neutralises the pond bottom sludge and accelerates its breakdown, pond bottom septicity is prevented. AQUA-Cal+ also allows a more rapid break-down of the sludge, which helps release organic material for the growth of phytoplankton (natural food for shrimp), while binding the toxic contaminants. Subsequently, the smell of the sludge is greatly reduced, with less toxic compounds in the water.

Better performance

Results from trials on both Pacific White Shrimp and Tiger Prawns show that AQUA-Cal+ has a superior performance to probiotics in controlling ammonia, nitrite and pond bottom sludge.

 

The data consistently shows AQUA-Cal+ stabilises alkalinity; suppresses extreme changes in pH; provides ingestible essential magnesium and calcium; reduces turbidity; improves light penetration; improves phytoplankton productivity; reduces toxic metals in the system (including copper and zinc); and reduces ammonia and nitrite.

Integrated supply chain

Calix's magnesite (magnesium carbonate) is mined and calcined in-house. Vertically integrated manufacturing means better service, reliability and performance.

Calix is certified ISO 9001:2015 for process development, manufacture, delivery and application of mineral based products.

Calix has established a network of local distributors and partners for AQUA-Cal+ to ensure customers receive excellent service and support, wherever they are located across the globe.

How it works

Utilising Calix’s platform technology, AQUA-Cal+ is made by flash calcining a mixture of magnesite and dolomite.

This produces a unique, high surface area powder, which is hydrated to produce a liquid slurry for ease of application to ponds. Dosing at the paddle wheel on a weekly basis throughout the grow out is required.

Case study

Reducing pollution while increasing yield

Following years of discharge of toxic sludge and wastewater into the waterways that fed a shrimp farm in Andhra Pradesh, AQUA-Cal+ improved water condition and reduced stress on the shrimp, helping to increase harvest weight and survival rates, whilst protecting the environment.

Sustainable Development Goals

Water sits at the heart of sustainable development.

Clean water and sanitation are a universal human right and underpin all economic development, poverty reduction and environmental sustainability.

Calix’s safe and sustainable products for water and wastewater management reduce pollution and minimise the release of hazardous chemicals and materials into our water systems.
