Our Solutions

Biological solutions for healthier ponds.

Our product range targets the fundamentals: water quality, microbial balance, and reduced chemical dependency. Developed by specialist biotech laboratories, distributed and supported by ELYN GROUP across Asia.

Probiotic Water Treatment

ELYN BIO digests organic matter, establishes a beneficial microbial baseline, and competitively excludes pathogenic Vibrio. It contains ≥ 6 × 1012 CFU/kg total viable count across 6 strains, ≥ 1 × 1012 CFU/kg per strain: Bacillus (2 species), Lactobacillus (2 species), Pseudomonas, and yeast. Apply 0.5 to 1 kg/ha weekly, continuous from pond preparation through harvest, at twice the standard rate before stocking. Increase 2 to 3 times at stocking densities of 60 to 150 PL/m². BIO is the foundation of the ELYN system.

ELYN DN controls the nitrogen cycle and suppresses toxic H₂S formation at the sediment-water interface - H₂S is the leading non-viral cause of shrimp mortality. DN contains ≥ 6 × 1012 CFU/kg across 6 strains, ≥ 1 × 1012 CFU/kg per strain, including dedicated nitrifiers (Nitrosomonas converts ammonia to nitrite; Nitrobacter converts nitrite to far less toxic nitrate). Apply 0.5 to 1 kg/ha in week 3 of the three-week cycle: BIO, BIO, DN. BIO and DN are never applied in the same week. Same density multiplier as BIO.

  • Organic load digestion and microbial baseline (BIO)
  • Competitive exclusion of Vibrio via space, resource, and antimicrobial chemistry (BIO)
  • Full nitrification chain plus H₂S suppression at the sediment interface (DN)
  • Freeze-dried powder, zeolite carrier, 5 kg aluminum bags - 2-year shelf life

Targeted Biological Controls

ELYN DGA captures excess phosphorus to starve algae at their nutrient source. Mineral-based - not a probiotic, not a chemical algaecide - calcium, magnesium, and aluminum compounds bind free phosphorus into stable apatite forms as the powder sinks through the water column.

At the bottom, DGA buffers acidic sediment, reduces H2S toxicity through mineral chemistry, and supplies Ca2+ and Mg2+ essential for shrimp moulting and shell hardening.

  • 77.4% algae removal in 10 minutes in laboratory tests; over 95% total reduction
  • pH buffering against day/night swings caused by photosynthesis cycles
  • Sediment mineralisation and mineral supplementation (Ca, Mg)
  • Mineral powder (100-150 mesh), 20 kg bags. Dose 5 to 20 ppm, or 60 kg/ha per application, 2 to 3 times per crop. Effective duration up to 1 month.

Note: These are starting rates. Actual dosing is set on the farm and must account for stocking density, pond history and carrying capacity, feed load through the cycle, and any other additives or treatments already in use. Microbial products control pollution only within the range of their biological activity; where load exceeds that range, more product will not compensate. See Farm Programs for detailed guidance.

Disease prevention pathway

Competitive exclusion & hydrogen sulfide

ELYN’s beneficial bacteria do not only improve water quality - they compete with pathogenic organisms (especially Vibrio species) for nutrients and colonization space. That competitive exclusion is part of how the system supports disease prevention alongside parameter control.

Hydrogen sulfide is a silent killer in shrimp farming: it forms under anaerobic sediment and is toxic at very low concentrations. ELYN DN is formulated specifically for H₂S removal alongside ammonia and nitrite - a benefit farmers should weigh as heavily as “nitrogen removal” alone.

Our Approach

Programs, not promises.

We do not sell miracle cures. Our products are backed by laboratory development and designed for real farm conditions. We focus on measurable, repeatable outcomes - the kind that show up in water tests and harvest results, not just marketing brochures.

Our products are manufactured by Korean labs and fermentation facilities. Specialized Korean biotechnology companies with dedicated fermentation and freeze-drying facilities. Developed with additional partners including leading laboratories from the European Union, specialising in microbial solutions for aquaculture. We handle everything from sourcing and quality assurance to regional distribution and technical guidance - so farmers get access to proven products with proper support behind them.

Korean knowhow of our partners in microbial aquaculture science from high-density shrimp and fish farming for 20+ years resulted in freeze-drying formulation methods behind ELYN's product stability.

Species Focus

Built for shrimp and fish farming.

Our current product range is developed and optimized for the two largest segments of Asian aquaculture: shrimp and fish pond farming. Whether you're running intensive vannamei operations or freshwater fish ponds, our biological products are formulated for the conditions and challenges you face.

  • Tilapia, all ponds including nursery, fry, grow-out, broodstock and breeding: ELYN BIO or ELYN DN at 1 ppm (1 g/m3) once weekly, twice if needed. Alternate BIO and DN where possible, or use either continuously. ELYN DGA 5 to 20 ppm per application, or 1 to 2 ppm weekly.
  • General fish ponds, per 1,000 tonnes of water: BIO 1 ppm per week, DN 1 ppm per week, DGA 5 to 20 kg per application or 1 to 2 kg per week.
  • Hatcheries, indoor facilities and RAS: BIO or DN 5 to 10 ppm per week. No DGA, algae-control products are not applied in enclosed systems.
