The fastest solution for removal of NH3 in prawn and fish pond




Moisture (max)                                                           : 12 %

Saponin (extracted from Yucca schidigera) (min)      : 10 g

Bacillus subtilis (min)                                                 : 1 x 109 CFU

Lactobacillus acidophilus                                            : 1 x 106 CFU

Saccharomyces cerevisiae (min)                                 : 1 x 108 CFU

Protease (min)                                                              : 500 IU

Amylase (min)                                                             : 15,000 IU

Carrier (starch) enough                                                : 1,000 g

Ethoxyquin (ppm)                                                        : None

Antibiotics                                                                    : None



  • Reducing NH3, H2S, NO2 in culture pond, limiting head-floating status.
  • Decomposing excessive wastes in pond bottom, limiting pollutions, making water color good.



  • Periodically 7-10 days using 300-500 g/1,000 m3 (0.1 ha)water metre depth).
  • When pond water is polluted, having lots of toxic gases: using 500-1,000 g/1,000 m(0.1 ha) (water metre depth) within 3 days continuously.
  • Dissolve YUCA Hong into water and spread evenly to the pond. The dosage based on the pond characteristics and the age of prawn.



  • Not use with other chemicals or disinfectants at the same time
  • The concentration of NH3 in cultured pond should be tested frequently to treat immediately.
  • Using frequently until harvesting                                       
  • Time to stop before harvesting: None.
