1g contains:

  • Bacillus subtilis:  1.2 x 108  CFU.
  • Bacillus licheniformis:  1.2 x 109  CFU.
  • Bacillus pumilus:  1.2 x 107  CFU.
  • Excipient q.s.f.: 1g.


  • Promote beneficial aquaculture microorganism and to inhibit the growth of pathogenic bacterial, especially Streptococcus spp., Aeromonas, Edwarsiella, etc.
  • To absorb and eliminate toxic gases in ponds: NH2, NO2, H2S, etc., which helps to reduce odors.

  • To improve water quality and stabilize pH in pond.
  • To improve the immune system and create a clean aquatic ecosystem for healther fishes with higher survival rate and rapid growth rate.


Dissolve 250g of  HAN-STREP POND into 190L of clean water and 10kg of molasses (for water color, suplement 10kg of rice bran) for 2 - 3 fermentation days in the tank using a cap.

  • To improve water color before 2 - 3 days of stocking: 20 - 30kg fermented liquid/1000m3  of water. Spread evenly throughout the whole pond in the mornings.
  • Periodic water treatment and prevention of Streptococcus spp., Aeromonas, Edwardsiella:  10 - 20kg fermented liquid/1000mof water for 5 - 7 consecutive days every morning.
  • For heavily polluted ponds or treatment of  Streptococcus spp., Aeromonas, Edwardsiella:  20 - 30kg fermented liquid/1000m3  of water for 5 - 7 consecutive days every morning.
  • For green algae (cyanobacteria) reatment: 20 - 30kg fermented liquid/1000m3  of water and spread throughout the whole pond for 2 - 3 consecutive days every evening (20:00 - 22:00).


  • Turn on the paddle-water and aeration system to utilize air-to-water contact to provide oxygen to the body of water, the probiotics need to be spread into the water to maximize product efficacy.
  • Do NOT use  HAN-STREP POND  concurrently with other disinfecting chemicals.
