NITROSOL (To fix nitrogen gases)

Aquaculture ponds receive relatively large amounts of organic and inorganic nitrogen inputs. Fish and shrimp assimilate about 20-25% of protein fed into their body and the rest is released to the pond as ammonia and organic nitrogen. In intensive aqua farming accumulation of unutilised feed, organic waste, dead algae increases load in the pond bottom, absorbing all the available oxygen thus creating anaerobic condition. In the absence of oxygen, noxious gases like H2S, NH3 and NO2 become more stable levels causing stress to the cultured species. Ammonia affects the central nervous system causing loss of equilibrium and in extreme cases it leads to death. Additionally ammonia increases the susceptibility of aquatic animals to infectious and non-infectious diseases. This ultimately leads to severe health problems and mortality in absence of corrective measures.

In nature microbes play a major role in nutrient recycling to enhance natural productivity and maintain water quality. Toxic forms of nitrogen viz. ammonia and nitrite are converted to nitrate and nitrogen gas through microbes involved in nitrogen cycle mainly through nitrification and denitrification processes. Nitrification is the process of biological oxidation of ammonia to nitrite followed by the oxidation of nitrite to nitrate. Nitrification involves two group of bacteria namely ammonia oxidizers (Nitrosomonas spp. and Nitrosococcusspp) and nitrite oxidizers (Nitrobacter spp., and Nitrospiraspp). Denitrification is a respiratory process, carried out by heterotrophic bacteria in which nitrate (NO3) and nitrite (NO2) are converted into gaseous nitrogen intermediates viz. nitric oxide (NO), nitrous oxide (N2O) and finally nitrogen (N2). The conversion reactions are very delicate and can be inhibited by high concentrations of organic ammonia and inappropriate PH.

Pool Fix contains blend of selective organisms known for their ability to stabilize the conversion process and to tolerate conditions of the pond. Pool Fix prevents ammonia build up, removes phosphorus, nitrogen compounds added to the pond water by shrimp faeces, unutilised food, dead algae and organic bottom sludge materials.
