High Ammonia Nitrite Emergency in Ponds: Fast Treatment with Microbial Probiotics

A sudden spike in ammonia and nitrite is one of the most frightening emergency conditions in shrimp and fish ponds. Within hours, concentrations of these toxic compounds can cause oxidative stress, gill damage, and mass mortality. If you face a high ammonia nitrite emergency in ponds, the first step is not massive water changes, but rather rapidly activating the biological nitrification pathway using high-concentration nitrifying bacteria. This article thoroughly examines the mechanisms, dosage, and application strategies of microbial probiotics to overcome this crisis, with a case study using the Ammonia & Nitrite Emergency Formula from Biosolution.

Why Are Ammonia and Nitrite Dangerous?

Ammonia (NH₃) and nitrite (NO₂⁻) are byproducts of protein metabolism in shrimp and fish. Under normal conditions, nitrifying bacteria oxidize ammonia to nitrite, then nitrite to relatively non-toxic nitrate. However, when the biological system collapses—due to overfeeding, plankton die-off, or decreased dissolved oxygen—ammonia and nitrite can accumulate drastically.

Ammonia Toxicity

Unionized ammonia (NH₃) is highly toxic because it easily penetrates gill membranes. At concentrations >0.1 mg/L, shrimp begin to lose appetite. At >0.5 mg/L, gill damage and mortality occur. Ammonia also increases oxygen consumption and disrupts osmoregulation.

Nitrite Toxicity

Nitrite enters the bloodstream through the gills and oxidizes hemoglobin to methemoglobin, which cannot carry oxygen. Consequently, shrimp and fish experience respiratory distress even when dissolved oxygen is adequate. Nitrite concentrations >1 mg/L are dangerous for vannamei shrimp.

The combination of high ammonia and nitrite creates a "double emergency" condition requiring immediate intervention. This is why every farmer must have a plan for emergency treatment of high ammonia and nitrite in ponds.

Role of Nitrifying Bacteria in Recovery

Nitrifying bacteria are key to the aquaculture nitrogen cycle. Two main genera are involved:

• Nitrosomonas sp.: Oxidizes ammonia (NH₃) to nitrite (NO₂⁻).
• Nitrobacter sp.: Oxidizes nitrite (NO₂⁻) to nitrate (NO₃⁻).

Both bacteria are aerobic and require dissolved oxygen >4 mg/L for optimal performance. In emergency conditions, natural nitrifying bacteria populations are usually insufficient to handle the nitrogen load spike. Therefore, adding large numbers of bacteria (shock dose) is necessary to accelerate nitrification.

Advantages of the Ammonia & Nitrite Emergency Formula

Biosolution designed the Ammonia & Nitrite Emergency Formula with Nitrosomonas sp. and Nitrobacter sp. concentrations 10 times higher than regular maintenance products. This enables:

• Ammonia oxidation begins within 2-4 hours after application.
• Significant nitrite reduction within 12-24 hours.
• Total water quality recovery within 24-48 hours.

The product is applied directly by broadcasting into pond water. The recommended dose for emergency conditions is 10 liters per hectare, sufficient for a single application. If levels have not dropped drastically after 24 hours, repeat with the same dose.

Application Strategy in Emergency Conditions

Here are tactical steps to take when detecting a high ammonia nitrite emergency in ponds:

1. Stop Feeding and Reduce Organic Load

Cease feeding for 24-48 hours. Feed residue and feces are the main sources of ammonia. Stopping feeding drastically reduces nitrogen load.

2. Increase Dissolved Oxygen

Nitrifying bacteria require high oxygen. Run paddlewheels or blowers at maximum. If necessary, add emergency aerators. Target dissolved oxygen >5 mg/L.

3. Apply Ammonia & Nitrite Emergency Formula

• Dose: 10 L/ha (shock dose).
• Time: Morning, when water temperature begins to rise.
• Method: Mix the product with pond water (1:10) then broadcast evenly.
• Monitoring: Measure ammonia and nitrite every 6 hours.

4. Add Lime or Dolomite (Optional)

If pH drops drastically due to nitrification, add dolomite lime to maintain pH 7.5-8.0. Optimal nitrification occurs at pH 7.5-8.5.

5. Evaluate and Repeat if Necessary

After 24 hours, remeasure. If ammonia or nitrite is still high, reapply at the same dose. Usually one application is sufficient, but extreme cases may require two.

Case Study: Vannamei Shrimp Pond Recovery

A farmer in Lampung experienced an ammonia spike to 2 mg/L and nitrite to 5 mg/L in a 0.5-hectare vannamei shrimp pond. Shrimp showed weakness, reduced appetite, and some mortality. He applied 5 liters of Ammonia & Nitrite Emergency Formula (equivalent to 10 L/ha) at 07:00. Monitoring results:

• 6 hours: Ammonia dropped to 1.2 mg/L, nitrite to 3.5 mg/L.
• 12 hours: Ammonia 0.5 mg/L, nitrite 1.8 mg/L.
• 24 hours: Ammonia 0.1 mg/L, nitrite 0.3 mg/L.

Shrimp became active again and appetite recovered after 36 hours. No additional mortality. The farmer saved an investment worth tens of millions of rupiah.

Comparison with Conventional Methods

Conventional methods like massive water changes or zeolite use are often less effective and costly. Water changes only dilute, not remove toxic compounds, and can stress biota. Zeolite only binds ammonia, does not oxidize it, so its capacity is limited.

In contrast, microbial probiotics like the Ammonia & Nitrite Emergency Formula biologically convert ammonia and nitrite into non-toxic nitrate. This process is sustainable as long as bacteria live and oxygen is available.

Advantages of Biosolution Products

• High concentration: 10x that of regular products, suitable for emergencies.
• Fast recovery: 24 hours, proven in the field.
• Easy application: Direct broadcast, no special equipment.
• Distributor margin: This product offers attractive margins for distributors, making pond business not only survivable but profitable.
