Yucca Gro Gold
Emergency aid for gasping shrimp · Removes toxic gas from the pond
An extract of the Yucca schidigera plant with at least 4.9% saponin. Broadcast over the pond, the saponin holds ammonium (NH₄⁺/NH₃) in the water, lowering toxic gas and reducing slime and odor. Just two ingredients: plant extract and distilled water.

How Yucca extract holds toxic gas
Yucca schidigera grows in the desert and its trunk is rich in saponin. The glyco fraction in the extract binds and holds ammonium, so free NH₃ in the water drops and shrimp breathe easier.

Fully natural
Nothing but Yucca extract and distilled water
Yucca schidigera grows in the deserts of Mexico and the south-western United States. Its trunk is rich in saponin, a natural compound that holds ammonium. YUCCA GRO GOLD is a concentrated extract of this plant in distilled water.
- Saponin from Yucca schidigera extract4.9% minimum
- Distilled waterto 1 litre
- Withdrawal before harvest: 0 daysCan be used right up to harvest.
- Liquid formDilute and broadcast; it spreads quickly through the pond.
- Use before probioticsClears toxic gas so the probiotics work better.
When to use
Four signs your pond needs YUCCA GRO GOLD
Shrimp gasping at the surface
Usually rising NH₃ — use the emergency dose.
High NH₃/NH₄⁺ test
After heavy feeding, an algae crash or a dirty bottom.
Slimy, smelly water
Organic matter building up in the pond.
Every 5 – 7 days
Before each probiotic application, to keep the water stable.
How it works
Saponin holds ammonium, so shrimp can breathe
- 1Toxic gas builds up
Leftover feed, shrimp waste and dead algae break down into ammonium. The toxic NH₃ part makes shrimp gasp at the surface.
- 2Saponin holds ammonium
Saponin in the Yucca extract binds and holds ammonium in the water, lowering the NH₃ the shrimp are exposed to.
- 3Cleaner water
Less slime, less odor. Shrimp return to feed, and probiotics applied afterwards work better.
Benefits

Directions
Dosage
| Use case | Dose | Frequency |
|---|---|---|
| Routine, during the crop | 500 g / 2,000 m³ of water | Every 5 – 7 days, before probiotics |
| Polluted pond, high toxic gas, gasping shrimp | 500 g / 500 – 700 m³ of water | As an emergency treatment |
How much YUCCA GRO GOLD for your pond
Enter the pond area and water depth, then pick the case.
How to use
Treat the pond in four steps
Shake well
Shake the bottle before pouring.
Dilute 50 – 100 times
Use clean water. 500 g goes into about 25 – 50 litres.
Broadcast evenly
Spread over the whole pond, not in one corner.
Run all aerators
Boost bottom oxygen during and after treatment.
Earthen black tiger shrimp ponds with a polluted bottom: mix YUCCA GRO GOLD with zeolite or mineral clay so it sinks quickly to the bottom for a faster response. Adjust the dose to pond conditions, stocking density and shrimp health. Close the cap tightly after use.
Use with
Clear toxic gas first, then apply probiotics
Apply YUCCA GRO GOLD first to bring toxic gas down, then use probiotics and enzymes to break down the organic matter at the source.
