A Complete Solution for Nitrites

A unique combination of optimized Colony Forming Units of Bacillus spp, Nitrifying and Denitrifying strains of Probiotics fortified with Yucca schidigera, Thiobacillus denitrificans, Nitrosomonas eutropha & Nitrobacter winogradskyi.

Nitrisol HP is highly potent in controlling nitrites levels in aqua ponds and reduces nitrates to nitrogen while oxidizing elemental sulphur or reduced sulphur compounds (S2-, S2 O32-, SO32-) to sulphates.


  • Bacillus megaterium:-
    • A fast growing bacteria & produces many digestive exo-enzymes into the environment.
    • Decomposes waste & excess organic matter thereby helps to keep the water clean.
    • Produces substances inhibiting the growth of undesirable bacteria, especially Vibrio spp.,
    • Solubilise phosphates.    
  • Bacillus subtilis:-                             
    • Produces many enzymes like Amylases, Proteases and Lipases etc.
    • Forms a symbiotic relationship with the hosts in the slime layers of fish / prawns.
    • Decomposes excess & waste organic matter & suppresses the growth of undesirable microbes
    • Helps the process of denitrification & converting Nitrates into Oxygen and Nitrogen
  • Bacillus licheniformis:-
    • Produces antibiotic like Bacitracin, which suppress the growth of undesirable microbes
    • Useful in degrading excess organic matter & waste materials like sediments & chitinous exoskeletons of the shrimps, because of its ability to produce the enzyme Keratinase.
  • Bacillus pumilis:-
    • Produces many enzymes for better pond health.
    • Suppresses the growth of molds / fungus.
    • Degrades waste organic matter & sediments to keep the water clean
  • Nitrosomonas eutropha and Nitrobacter winogradskyi:-
    • These probiotics are most effective in removing nitrite and ammonia levels.
    • Nitrobacter oxidizes nitrites which are a by-product of Nitrosomonas and coverts into Nitrate, which is then available for plants as nutrient. Both Nitrosomonas and Nitrobacter together remove the toxic Ammonia from the pond water and keep it clean.
    • Nitrosomonas eutropha is able to oxidize 1000-1200 molecules of ammonia/kg/hr &  Nitrobacter winogradskyi is able to oxidize 250-300mg nitrite/kg/hr which helps to  immediately reduce the ammonia build up in the pond meanwhile, bacillus strains added help to hasten the breakdown of the rotting organic material which is producing the excess ammonia.
  • Thiobacillus denitrificans:-
    • Belongs to the class of obligate chemo litho autotrophic and facultative anaerobic microorganisms.
    • Reduces nitrate to nitrogen gas while oxidizing elemental sulphur & reduced sulphur compounds (S2-, S2 O32-, SO32-) to sulphate, thereby eliminating the need for organic compounds.
    • Remediates the natural  groundwater & engineered water treatment systems by removing excess nitrate with coupling the oxidation of inorganic sulphur compounds to the reduction of oxidized nitrogen compounds (such as nitrate, nitrite). 
  • Yucca schidigera:-
    • Rich source of Glyco fraction extracts to effectively bind the free ammonia
    • Polyhydroxy stilbene in Yucca performs the urease-inhibiting activity
    • Improves water quality and consequently the farm productivity


  • Most effective for removing nitrites from pond water              
  • Converts nitrites into nitrates to improve water quality
  • Converts nitrates into nitrogen                                                      
  • Decompose waste & organic matter                                             
  • Suppresses the growth of undesirable microbes in pond             
  • Removes nitrogen from pond effectively                                        
  • Converts nitrates into oxygen                                                           
  • Prevent growth of Vibrio spp in ponds                                 
  • Degrades organic matter & reduce growth of fungus             
  • Solubilises phosphates & cleans the pond water                     
  • Binds free ammonia in the pond & improves water quality          
  • Oxidizes elemental sulphur or reduces sulphur compounds (S2-, S2 O32-, SO32-) to sulphate
  • Decompose waste, organic matter and suppresses the growth of undesirable microbes in pond
  • Breaks the cycle of formation of Nitrites in aqua ponds         


The solution prepared by mixing Nitrisol Pack 1 & Pack 2 should be mixed in one acre of pond water or as advised by an Aquaculture Consultant/Expert.
