Water Program

ELYN Water Program

Baseline (BIO), Prevention (DN), Surface Layer / Sediment (DGA).

Pond pH, dissolved oxygen, nitrogen, organic matter, and algae are all interconnected — you cannot treat one in isolation and expect stability. The ELYN Water Program uses three products working together because each targets a different part of this system.

Improved water and sediment quality lowers environmental stress on shrimp — the primary trigger for disease outbreaks. Stressed animals show suppressed immune function and higher susceptibility to viral and bacterial pathogens. This program addresses root causes in the pond environment rather than treating symptoms.

Baseline

ELYN BIO

Water & Aquatic Quality Improver

Microbe-enhanced water purifier with 7 microbial strains. Decomposes organic matter, stabilizes water color, improves bottom soil, and supports pathogen control. Includes phototrophic bacteria which oxidise hydrogen sulfide (H₂S) using light energy, fix nitrogen, and improve water clarity. Used continuously from stocking through harvest.

Total viable count: ≥ 2.4 × 10¹² CFU/kg (7 strains; individual strain densities vary)
Freeze-dried powder on zeolite carrier — extended stability; shelf life up to 2 years
Bacillus strains are spore-forming — guaranteed viable through processing, storage, and gut passage
Powder formulation: strains blended post-drying to limit inter-strain competition vs. many liquid products
Works in both freshwater and seawater
Entirely facultative anaerobes (effective in anaerobic sediments)
Packaging: 5 kg bag
Guidance: 1 kg/week per acre

Prevention

ELYN DN

Nitrogen Remover

High-efficiency nitrogen decomposer targeting ammonia, nitrite, and hydrogen sulfide (H₂S) — H₂S forms in anaerobic sediment and is extremely toxic at low concentrations. DN is formulated for H₂S removal in both water column and sediment. Apply when sediment deteriorates or nitrogen indicators rise.

Microbial density: ≥ 5 × 10¹² CFU/kg
Freeze-dried powder on zeolite carrier — shelf life up to 2 years
Effective across pH and salinity ranges
Packaging: 5 kg bag
Guidance: 1-5 kg/ha/week (condition-adjusted)

Surface Layer / Sediment

ELYN DGA

Green Algae Remover

Mineral-based algae management: calcium, magnesium, and aluminum compounds bind free phosphorus into stable apatite forms that algae cannot use — not a chemical algaecide. Improves water quality (BOD, COD, turbidity), enhances bottom sediment and soil conditioning, and supplies minerals for shrimp health. Apply when bloom indicators are confirmed.

Deployment data: 77.4% algae reduction within 10 minutes (often visible as water color change)
Sediment improvement alongside bloom control
Slightly alkaline — supports higher bottom pH, reducing H₂S toxicity
Calcium, magnesium, and aluminum for shell formation and overall health
Safety tested: harmless at 10× recommended dose (200 ppm)
Packaging: 20 kg bag
Guidance: 5–20 ppm; typically ~3 applications per 4-month cycle when blooms are severe (as needed)

Application timing: ELYN BIO continuously from early stages through harvest. ELYN DN as needed for sediment improvement and nitrogen (including H₂S) control. ELYN DGA when algae growth is severe — typically around three applications in a 4-month cycle. Dosing varies by growth stage because feed intake and waste generation change through the cycle.

Note: Adjust the dosage according to pond conditions during the culture cycle, and increase the dosage as feed input increases.

How the cycle works

Week 0
Prepare pond: BIO + DN
(3-day difference)

Week 1
BIO
(2 days after seed stocking)

Week 2
DN
(5 days after BIO)

Week 3
BIO
(4 days after DN)

Then alternate BIO + DN every 5-6 days until end of cycle. Monitor water parameters and adjust as needed or reach out to ELYN GROUP technical support for advice.

DGA: apply when algae growth is severe — typically around three times per 4-month cycle, with dose varying by growth stage as feed intake and waste load change.

Why this works as a system

ELYN BIO handles organic decomposition and sediment conditioning — the baseline load that drives oxygen demand and nitrogen stress. ELYN DN targets ammonia, nitrite, and hydrogen sulfide in water and sediment — including H₂S, which is lethal at trace levels easily achieved on pond bottoms. ELYN DGA manages algae and phosphorus plus bottom buffering and minerals — closing the loop when blooms and nutrient imbalance threaten the system.

Together they create a stable pond environment. That integrated approach is a key differentiator versus single-product programs.

Algae reduction with DGA within 10 minutes (deployment data)

Expected results timeline

From commercial deployment experience:

Water quality improvements often visible within about one month
Growth rate and mortality improvements commonly assessed 4–8 weeks before harvest
With DGA, strong algae reduction within 10 minutes is often visible through water color change

Observed results from commercial deployment. Results vary by species and environmental conditions.

Program outcomes vary by stocking density, feed load, aeration, salinity, and farm operations. Dosage and timing decisions should be based on field measurements and technician guidance. Performance data references historical results from Korean and international farm operations and may not directly predict outcomes in all conditions. All statements on this page describe support programs and do not represent treatment guarantees.

All ELYN water-program products are antibiotic-free. Fish toxicity testing reported harmless at 200 ppm (10× recommended dose); Daphnia non-toxic at 50+ ppm. Classified as supplementary feed under Korean regulations. Over 20 years of formulation history on Korean shrimp farms.
