Pond Bottom Sludge Decomposer Without Draining: Solution for Intensive Farmers

Pond bottom sludge is a nightmare for intensive shrimp and fish farmers. Accumulation of uneaten feed, feces, and dead plankton forms sludge that releases ammonia and degrades water quality. The common solution has been periodic pond draining—high cost, biota stress, and waste. However, there is a smarter approach: using decomposer microbes. Biosolution presents the Pond Bottom Sludge Decomposer Formula utilizing Bacillus subtilis and Bacillus licheniformis to naturally decompose sludge, keeping the pond clean without draining.

Why Is Pond Bottom Sludge a Critical Problem?

In intensive aquaculture systems, high stocking density and overfeeding cause organic matter accumulation at the pond bottom. This sludge consists of proteins, fats, carbohydrates, and nitrogen compounds that are not yet decomposed. Anaerobic decomposition by pathogenic bacteria produces ammonia (NH₃), nitrite (NO₂⁻), and toxic gases like H₂S. Ammonia levels above 0.1 mg/L become toxic to shrimp and fish. Additionally, sludge provides an ideal medium for pathogenic Vibrio spp. bacteria. If left unchecked, pond productivity plummets and the risk of mass mortality increases.

Mechanism of Action of the Pond Bottom Sludge Decomposer Formula

This formula contains two superior probiotic bacteria: Bacillus subtilis and Bacillus licheniformis. Both are gram-positive, facultative aerobic bacteria capable of producing extracellular enzymes such as protease, amylase, lipase, and cellulase. These enzymes break down complex organic molecules into simple compounds that can be utilized by other microbes or absorbed by phytoplankton. Bacillus subtilis is known as a primary decomposer, while Bacillus licheniformis enhances enzymatic activity. Their synergy accelerates sludge degradation by up to 70% faster compared to untreated conditions.

Proper Application: 1 Tablet per 50 m² Every 14 Days

For optimal results, apply by spreading tablets directly on the pond bottom in the morning. The recommended dosage is 1 tablet per 50 m² of pond bottom area. The tablets are designed to sink and slowly dissolve, releasing bacteria and enzymes gradually. Application every 14 days ensures a stable bacterial population. This method is very practical, requiring no special equipment or stopping water circulation. Farmers can apply it while performing other routine activities.

Key Advantages

• Decomposed Bottom Sludge: Organic sludge is drastically reduced, pond bottom becomes cleaner.
• Significant Ammonia Reduction: Degradation of organic nitrogen suppresses ammonia release by 50-60% within 7 days after application.
• No Need for Pond Draining: With routine application, sludge accumulation is controlled, so draining is only needed at the end of the cycle.
• Cost Savings: Reduces frequency of draining, water consumption, and waste treatment costs.

Comparison with Conventional Methods

Conventional methods like manual draining using pumps require electricity, labor, and time. Moreover, draining causes stress to biota due to sudden environmental changes. By using the Pond Bottom Sludge Decomposer Formula, farmers can maintain stable water quality throughout the cycle. The table below shows the comparison:

Water Quality Management Strategy per Culture Phase

Early Phase (1-30 Days)

In this phase, water quality is still good due to low organic load. However, prevention remains important. The first application of the Pond Bottom Sludge Decomposer Formula is done on day 7 after stocking. Dosage: 1 tablet per 50 m². The goal is to establish a Bacillus population on the pond bottom so that when organic load increases, the bacteria are ready to work.

Mid Phase (31-60 Days)

Feed input increases, sludge begins to form. Second application on day 21, third on day 35, and so on every 14 days. In this phase, ammonia reduction becomes significant. Regular monitoring using test kits is recommended to track effectiveness.

Late Phase (61-90 Days)

Peak organic load occurs. Applications continue every 14 days. In this phase, the greatest benefits are felt: the pond bottom is not thickly muddy, ammonia remains low, and shrimp/fish are healthier. Draining is only done at harvest, saving operational costs by up to 30%.

Supporting Data and Scientific References

Research from FAO shows that Bacillus spp. probiotics effectively reduce total ammonia nitrogen (TAN) and improve survival of vannamei shrimp. Meanwhile, a study from IRRI confirms that using decomposer bacteria in aquaculture ponds reduces greenhouse gas emissions. Biosolution adopts similar technology with formulations tailored for Indonesian tropical conditions.

Farmer Testimonials

Mr. Sugeng, a vannamei shrimp farmer in Lampung, said that after using the Pond Bottom Sludge Decomposer Formula, he no longer needs to drain his pond mid-cycle. "Previously, I drained every month, shrimp stressed, many died. Now I just apply the tablet, ammonia drops, shrimp are healthy, harvest increased by 15%," he said. Similar testimony came from Mrs. Dewi from South Sulawesi, who saved operational costs up to IDR 7 million per cycle.

Proper Usage Instructions

1. Calculate the pond bottom area (length x width).
2. Divide by 50 to get the number of tablets per application.
3. Spread tablets evenly over the entire pond bottom surface in the morning.
4. Repeat every 14 days until harvest.
5. Ensure aeration is running normally to support aerobic bacterial activity.

Conclusion

Pond bottom sludge is no longer a complicated problem. With Biosolution's Pond Bottom Sludge Decomposer Formula, intensive farmers can manage water quality efficiently without draining. The Bacillus subtilis and Bacillus licheniformis technology works naturally to reduce ammonia and decompose sludge. The dosage of 1 tablet per 50 m² every 14 days is the key to success.

FAQ

1. Is this product safe for shrimp and fish? Yes, Bacillus subtilis and Bacillus licheniformis are safe probiotics widely used in aquaculture. They are non-pathogenic and actually suppress harmful bacteria. This product has been tested on various pond scales with no negative side effects.

2. How long does it take to see decomposition effects? Initial effects are usually visible within 3-5 days after application, such as reduced ammonia and odor. Sludge begins to decompose significantly within 7-14 days. For optimal results, routine application every 14 days is necessary.

3. Do I need to stop aeration during application? No. Aeration should continue to help distribute bacteria and enzymes on the pond bottom. Good aeration actually supports the work of aerobic bacteria in decomposing sludge.

4. What if the pond is already heavily silted? If sludge is very thick (>10 cm), apply double the dosage on the first application (2 tablets per 50 m²), then continue with normal dosage every 14 days. Sludge will gradually decompose within 1-2 months.

5. Can this product be used together with water probiotics? Yes. The Pond Bottom Sludge Decomposer Formula works on the bottom, while water probiotics work in the water column. Both complement each other to maintain overall water quality. Ensure no antagonism by reading the water probiotic product label.
