NEW
A complete microbial solution for super-intensive pondsBiological Solution for Environmental Management in Super-Intensive Aquaculture. High-count Bacillus subtilis and Bacillus licheniformis: takes up NH3, speeds up nitrification, breaks down organic matter and uneaten feed, and helps the pond settle quickly after an algae crash or bloom.

How SOILMAX New stabilises the pond
High density, heavy feeding — the pond changes fast
- 1
Organic build-up
Uneaten feed and droppings settle; water and bottom get dirtier.
- 2
NH3 and NO2 rise
Decaying waste releases toxic gases; slow nitrification lets NO2 accumulate.
- 3
Algae crash
Algae bloom then die off and the pond loses stability mid-crop.
- 4
Red or dark water
Algae blooms change the water color and make it thick.
4 main benefits
- 01
Balance pond water quality through: NH3 absorption, accelerating nitrification process, counteracting NO2 formation.
- 02
Establish stable beneficial microbial populations at high levels, decompose organics, excess feed, and clean water and pond bottom.
- 03
Rapidly stabilize the environment and quickly promote the start of a new cycle during the algae decline or algae collapse phase.
- 04
Treatment to restore the pond environment during algal bloom, red water or dark-colored water, with high water turbidity.
Two high-count Bacillus strains keep the pond in balance
In super-intensive ponds, uneaten feed and waste break down into NH3; if nitrification is slow, NO2 builds up. SOILMAX New adds a stable, high-level population of beneficial microbes: it breaks down organic matter, takes up NH3, speeds up nitrification and counters NO2 formation — and helps the pond restabilise quickly after an algae crash or bloom.
The nitrogen cycle in the pond and what the microbes do
- Uneaten feed, droppingsBreak down organic matter
- NH3 / NH+4Take up NH3
- NO−2Counter NO2 formation
- NO−3Speed up nitrification
- 01
Organic breakdown
A stable, high-level beneficial population digests uneaten feed and cleans the water and pond bottom.
- 02
Nitrogen cycle
Takes up NH3, speeds up nitrification and counters NO2 formation.
- 03
After an algae crash
Quickly stabilises the environment and kick-starts a new cycle.
- 04
During an algae bloom
Restores the pond when the water turns red or dark and gets thick.
Dosage by pond condition
Per the 2026 catalogue. 1 bag = 227 g.- Routine use1 bag / 2,000 – 2,500 m³ of waterRepeat after 3 – 5 days
- Heavy pollution — algae bloom, red or dark water, thick water1 bag / 1,000 m³ of water2 – 3 days in a row
2 ways to use
- 2 hActivate firstAerate the bag with a biomass nutrient (cane sugar or molasses) and about 20 litres of water for 2 hours before use.
- 30 LApply directlyMix the product with 30 litres of water, spread evenly over the pond and run all paddlewheels while applying.
iBest applied at 9 – 10 AM. To cut algae, apply at 11 PM for 2 nights in a row. Ponds with heavy blue-green or red algae can combine it with OZYME for faster results.
Adjust the dose to the actual pond condition, stocking density and shrimp health. Seal and zip the bag right after use if not finished.

SoilMax is a blend of living microorganisms from natural environments, rigorously screened based on criteria: survival capability, biological treatment, beneficial functions, waste digestion, and pathogen inhibition feasibility. Specially selected to provide effective and flexible solutions for biological treatment in aquatic environments under all intensive aquaculture conditions in aquaculture.
SoilMax naturally reduces organic waste, helps maintain water quality, controls algal blooms, and promotes a positive microbial environment at the highest level.
SoilMax and the difference
- Combines 6 different Bacillus strains.
- All microbial blends are systematically selected to ensure the most comprehensive biological treatment of organic substances. To develop applications of this product, the microbial strains in the product are derived from the largest beneficial microorganism collection of marine origin - over 10,000 strains collected worldwide.
- Through a rigorous screening process based on the following criteria:
- Treatment microorganisms must be based on their ability to survive under harsh pond conditions.
- Beneficial functions for biological treatment - digestion of diverse organic matter, combined treatment with balanced enzyme systems contained in the product.
- Inhibiting harmful bacteria is an important feature of the product. These microbial strains create a competitive advantage for inhibiting pathogens caused by bacteria in ponds.
- Through multiple selection criteria, SoilMax has high stability in storage.
- Flexible and effective treatment in all pond environments.
Comprehensive microbial solution for intensive aquaculture ponds
Product description
- SoilMax is a ready-to-use formulation that does not require prior biomass activation.
- SoilMax works under varying pond conditions. SoilMax contains selected microorganisms to maintain biological activity consistently within a wide range of: salinity, temperature, and dissolved oxygen content.
- A combination of a special microbial system and balanced enzyme system for diverse biological treatment of complex organic waste.
- SoilMax promotes and stabilizes a positive aquatic microbial environment and creates the highest population of beneficial microorganisms in the pond.
Instructions for use
- Regular use: 1 packet/2,000 - 2,500 m3 of water, repeat after 3 - 5 days.
- Heavy pollution treatment in case of algal bloom, red or dark water, high water viscosity: 1 packet/1,000 m3 of water, use continuously for 2 - 3 days.
- Best used at 9 - 10 AM. In case of algae cutting, dose at 11 PM. Dose 2 consecutive nights. If the pond has excessive blue-green algae or red algae, it can be combined with OZYME for faster treatment.
Note:
There are 2 methods of use:
- Aerate the product packet with microbial biomass nutrients/cane sugar or molasses with approximately 20 liters of water for 2 hours before use.
- Direct use: Mix the product with 30 liters of water, dose directly into the pond, turn on all water aerators during product use.
Depending on the actual pond condition, stocking density, and shrimp health, increase or decrease the dosage as appropriate.
Seal and zip the bag immediately after use if the product is not completely used.
Storage
