Natural tea-color water conditioner — stabilizes the pond environment, healthy fast-growing shrimp. Concentrated fulvic acid on a yeast base, colors the pond through nutrition, not chemicals.

Quality specifications registered under TCCS 02:2026/TV.
Fulvic acid and potassium dissolve fast in water; the inactivated-yeast base is an organic substrate — diatoms and beneficial microbes can use it right away.

Fulvic acid + K₂O dissolve fast, spread evenly through the water column

Stimulated to grow — water turns a natural tea color

Beneficial microbes multiply, breaking down organic waste

Abundant natural food, less pH swing, cleaner bottom
Natural tea-color water, stimulates diatom growth
Builds a natural food source, stabilizes the bottom — environment
Stabilizes pH, reduces environmental swings
Builds a biological floc system, breaks down organic waste

Apply on a sunny morning, keep paddlewheels running for even distribution. Read the label carefully before use.
The root cause of common pond issues, the production process, a comparison with molasses & humic minerals, a dosage table for 6 pond sizes, a season-long usage schedule, and frequently asked questions.
If your pond is facing one of these three, this section is for you.
You apply fermented feed or bran — water stays clear, or a poor algae bloom forms then crashes. Post-larvae lack natural food in the very first week.
NH₃, NO₂, H₂S rise gradually from mid-crop onward. Water changes cost money and bring in disease risk from outside.
Chemical treatment also kills off beneficial microbes. The pond grows "weaker" over time, and treatment costs keep climbing.
A nutrient concentrate obtained by fermenting Saccharomyces cerevisiae yeast on a molasses base, then filtering out the spent yeast and drying it into a powder.
This is FEED for microbes and algae — there is no living bacteria in the bag. No risk of dead cultures, no cold storage needed, stays effective long-term.
Molasses is only the input material. Through fermentation, the yeast has already "cooked" the sugar into protein, vitamins, minerals and other valuable compounds.
Nutrients are already dissolved in water — microbes and algae can take them up immediately, no need to wait for decomposition.

Main raw material, rich in fermentable sugar

Saccharomyces cerevisiae yeast

Yeast "cooks" the sugar into protein, vitamins, valuable actives

Keeps the nutrient-rich liquid fraction

Four main nutrient groups — kept simple and memorable.
Three things farmers commonly apply to ponds — three very different natures. The lower the C/N ratio, the easier for microbes to "eat".
Has sugar plus protein, minerals, and vitamins — a full course meal. Microbes multiply the moment they consume it.
Sugar only, almost no protein — like plain rice with nothing to go with it. Cheap, and can be used alongside FYTO FLOC, each playing a different role.
Extracted from coal, hard as rock — microbes can barely consume it. Only tints the water, doesn't feed the microbial community.
Three benefits that chain together like a production line.

Produces toxins, makes water slimy; mass die-off at night pulls oxygen down sharply — a familiar culprit behind shrimp gasping at the surface.

Safe for shrimp and fish, gives a stable banana-leaf-green water color — and doubles as good feed for Daphnia and Moina.

Gives a nice water color, releases oxygen during the day, feeds Daphnia and Moina

The smallest live feed — sized right for fry and freshly-stocked post-larvae

Multiply fast once the pond has enough algae — the main feed for fry and small shrimp

Rich in protein and good fats for post-larvae and fry
Pre-calculated for 6 common pond sizes, based on the 3–5 kg initial dose and 3 kg / 1,000 m³ maintenance framework.
| Water volume | Reference pond | Initial · per application | Maintenance · per application | Maintenance · per month |
|---|---|---|---|---|
| 500 m³ | 500 m² · 1.0 m deep | 1.5 – 2.5 kg | 1.5 kg | 6 – 7.5 kg |
| 1,000 m³ | 1,000 m² · 1.0 m deep | 3 – 5 kg | 3 kg | 12 – 15 kg |
| 2,000 m³ | 2,000 m² · 1.0 m deep | 6 – 10 kg | 6 kg | 24 – 30 kg |
| 3,600 m³ | 3,000 m² · 1.2 m deep | 11 – 18 kg | 11 kg | 43 – 54 kg |
| 6,000 m³ | 5,000 m² · 1.2 m deep | 18 – 30 kg | 18 kg | 72 – 90 kg |
| 12,000 m³ | 1 ha · 1.2 m deep | 36 – 60 kg | 36 kg | 144 – 180 kg |

Calculate based on pond water volume. Weigh it out on the bank — don't estimate by scoop or can.

Dissolve in a bucket of pond water, stir until fully dissolved before applying. Don't scatter dry powder.

Stand upwind and apply, then run paddlewheels to mix it evenly through the whole pond.

Algae "feed on sunlight" right away, while oxygen levels in the pond are rising.
Example: a 3,000 m² pond, 1.2 m deep — about 3,600 m³ of water. Adjust to match your own pond.
5–7 days before stocking. Let the water reach a good, stable color before stocking post-larvae.
Maintain water color, feed Daphnia/Moina for the young shrimp.
Switch to light, even applications — the pond starts accumulating more waste.
The month toxic gas rises fastest — keep the same rhythm, don't stretch out the interval.
Molasses is like uncooked rice — microbes have to "cook" it before they can use it. FYTO FLOC is ready-cooked rice, complete with protein, minerals, and vitamins. If you're already using molasses, keep using it: molasses supplies bulk, FYTO FLOC kickstarts and enriches.
No. This is FEED for microbes — there is no living bacteria in the bag, so there's no risk of dead cultures, no cold storage needed, and it stays effective long-term.
To be honest: it doesn't treat any disease — this is a water-care, pond-care product. Good water means less stress and less disease for shrimp and fish — prevention over cure.
Wait a full 3 days after disinfecting or applying antimicrobials — during those 3 days keep paddlewheels running to clear residue, then apply FYTO FLOC or your probiotic.
