AQUACULTURE WATER TREATMENT WITH CHLORINE DIOXIDE SOLUTIONS

SAFE & EFFECTIVE WATER TREATMENT FOR AQUACULTURE

Aquaculture Water Treatment is essential for maintaining fish and shrimp health, preventing disease outbreaks, and ensuring seafood safety. Using Chlorine Dioxide (ClO₂) solutions like CDD 5000, CHLORITAB, and CHLORONE, aquaculture businesses can eliminate harmful pathogens, control biofilm formation, and enhance water quality without harmful byproducts.

Chlorine dioxide is very different from elementary chlorine, both in its chemical structure as well as in its behavior. Chlorine Dioxide is revolutionizing the aquaculture industry by providing a safe and effective solution for fish and shrimp farming, seafood processing, and disease control.

APPLICATION OF ClO2 IN AQUACULTURE WATER TREATMENT

CDD 5000 / CHLORONE / CHLORITAB in Pond Preparation

CDD 5000 is widely used in pond preparation against conventional chlorination by Bleaching powder/Tropical Chloride of Lime.

Advantages of CDD 5000 in Aquaculture:

  • No drop in pH. pH is maintained as it was of the water.
  • No Increase in Hardness of water. 
  • No drop in Alkalinity of water. 
  • Additional chemical requirement (Lime or Sodium carbonate). 
  • Can control Vibiro count/colonies. 
  • Dechlorination/chemical neutralisation time 100% less at least as compared to chlorine. 
  • Labour requirement negligible. 

For best practices, refer to the World Aquaculture Society Guidelines.

CHLORINE DIOXIDE FOR DISEASE PREVENTION IN FISH & SHRIMP FARMING

Chloritab for Disease Control

CHLORITAB, with its innovative formulation, can be used from 15 days of age up to harvesting for disease control in the pond. When used in a prescribed manner, it does not affect the crop. It has various benefits for the pond water chemistry. 

  • Deactivates excess organic load. 
  • Reduces unwanted algal density. 
  • Reduces Vibrio Load. 
  • Deactivates bacteria, protozoa, fungi, etc in water. 
  • Reduces Hydrogen sulfide levels in water. 

CHARACTERISTICS OF ClO2 IN AQUACULTURE WATER TREATMENT

Why use Chlorine Dioxide in aquaculture water treatment?

  • Reduce Nitrite (NO2-) rapidly 
  • Get rid of odorous soil of animals in culture system 
  • Effect quickly and without toxic remnant 
  • Dissolved oxygen increasing 
  • Decrease the stress of fish in ponds and enhance the rate of feedstuff.

FAQs ABOUT CHLORINE DIOXIDE AQUACULTURE WATER TREATMENT

It controls harmful bacteria, algae, and parasites without harming fish. SVS Aqua offers safe formulations for pond and tank systems.

Yes, when used in the right concentration. SVS Aqua tablets come with precise dosing instructions for aquaculture use.

Yes. Cleaner water reduces disease stress and promotes better feed conversion ratios.

Frequency depends on water load and season. SVS Aqua recommends weekly or bi-weekly use depending on water quality.

It can reduce the dependence by preventing infections, but it should be part of an overall health management strategy.

Chlorine dioxide is gentler on aquatic life, more effective at killing pathogens, and doesn’t form harmful residues like chlorine.

Bleach can harm fish gills and alter pH, whereas chlorine dioxide works at lower, safer concentrations. SVS Aqua has aquaculture-specific tablets.

Yes, but with careful dosage. It's often used before stocking to sanitize tanks and ponds.

Yes, but in moderation. SVS Aqua can guide usage in BFT systems without disrupting microbial balance.

It keeps pathogens under control, improves oxygen levels by reducing organic load, and helps maintain a stable environment.
