The discharge of faecal matter by the shrimp/fish into the pond adds to the toxicity of the water. This deterioration of the water quality increases the culture's susceptibility to stress and disease. The partially decomposed sludge starts breeding  pathogenic bacteria such as Vibrio cholera. High amount of toxic wastes induces blue green algae to thrive, and become unstable, the incidence of disease and stunted growth increases, and mortality rates soar.

Biopristine Aqua is a proprietary blend of carefully selected naturally occurring microorganisms, enzymes and growth stimulating factors. It is a balanced formula of different microbial strains, which work synergistically to lower the toxicity level in the pond and create a healthier and more beneficial environment for fish, prawn and shrimp. The toxic pollutants are broken down to non-toxic by-products such as carbon dioxide and water. This is also evident when there will be a remarkable reduction in foul odours in the pond water.The number of water exchanges can be reduced by using Biopristine Aqua.
