SHRIMP POND WATER TREATMENT: DISEASE CONTROL & HIGHER PRODUCTIVITY
In modern aquaculture, shrimp pond water treatment is not simply about changing water.
In reality, it involves managing an entire complex ecosystem. To achieve successful farming results, farmers must maintain clean, oxygen-rich water.
At the same time, keeping water quality parameters stable is the most important foundation. These factors help shrimp grow faster and improve survival rates.
This is the key to maximizing profits after every farming season.
1. Disinfection and Stabilization of Water Parameters at the Beginning of the Crop
The pond preparation stage and the first month of farming are the most sensitive periods.
Early pathogen control through shrimp pond disinfection can reduce up to 70% of disease risks later in the culture cycle.
Techniques for Stabilizing Alkalinity and pH in Shrimp Ponds
pH and alkalinity act as a “shield” protecting shrimp from weather fluctuations.
Ideal pH: 7.5 – 8.5
Ideal alkalinity: 120 – 150 mg/L
To maintain stable alkalinity and pH, farmers should monitor these parameters twice daily (morning and afternoon).
Apply calcium lime or specialized mineral supplements after heavy rains to prevent environmental shock and molting problems.
How to Create Natural Water Color for Shrimp Ponds
Tea-colored water (caused by diatom algae growth) is considered the ideal pond water color.
An effective way to create this color is by using probiotics combined with rice bran and molasses fermented for 24 hours.
This beneficial algae system not only provides a natural, nutrient-rich food source for juvenile shrimp, but also prevents the growth of bottom algae and harmful algae species.

2. Solutions for Treating Slime Water and Controlling Harmful Algae
As shrimp ponds enter intensive farming stages, increased feed and waste accumulation can cause foam, slime, and blue-green algae blooms on the water surface.
These are warning signs of severe organic pollution.
Biological Treatment for Slime Water in Shrimp Ponds
Slimy pond water is caused by excess proteins and lipids that have not been fully decomposed.
Solution: Use concentrated enzymes such as Protease and Amylase to break down organic slime.
This helps:
Clarify pond water
Increase dissolved oxygen
Stabilize the pond environment
How to Control Blue-Green Algae and Stabilize Water Color at Night
Blue-green algae release toxins that negatively affect shrimp digestion and reduce oxygen levels at night.
Safe treatment method: Apply probiotics between 10 PM and 2 AM.
This helps:
Control algae growth
Prevent sudden algae crashes
Reduce shrimp surfacing behavior caused by oxygen depletion
Timely treatment of slimy water and blue-green algae helps protect shrimp gut health and overall vitality.

3. Application of Biological Products to Treat Water and Toxic Gases NH3, NO2
Instead of overusing harsh disinfectant chemicals that can stress shrimp, using biological water treatment products is becoming a more sustainable solution.
Beneficial microorganisms naturally “clean” the pond environment.
Effective Removal of Toxic NH3 and NO2 from Pond Bottoms
Toxic gases are produced by oxygen-deficient organic decomposition at the pond bottom.
To effectively remove NH3 and NO2, farmers should supplement specialized bacterial strains such as:
Nitrosomonas
Nitrobacter
These bacteria convert highly toxic NH3 into NO3, a less harmful fertilizer form.
This process requires high dissolved oxygen levels.
Therefore, farmers should increase aeration while applying probiotics for faster and more effective treatment.
Using probiotics helps eliminate NH3 and NO2 at the pond bottom, maintaining a safe environment for shrimp.
Benefits of Applying Probiotics Every 5–7 Days
Regular probiotic application helps:
Maintain a clean pond bottom by decomposing dead algae, waste, and shrimp shells
Suppress harmful bacteria, especially Vibrio that causes hepatopancreatic diseases
Reduce costs by minimizing the need for frequent water exchange and stabilizing the pond environment throughout the farming season
