Ammonia
Ammonia in water basically stayed in two form unionized Ammonia (NH3)
and Ammonium ion (NH4 ). Unionized ammonia is very much lethal and
predominated when PH is high. In pond environment PH up
and down due to photosynthesis and respiration by pond organisms. Waste
nutrients concentration from feed and feases promote dense phutoplankton.
During day time in the presence of sunlight phytoplankton produce their own
food by photosynthesis process. Day time CO2 is being low and due to rapid
photosynthesis , removal of Carbon dioxide ( CO2) converted to
carbonate ( CO3) and bi carbonate (H2CO3) and pH become high but at
night time when CO2 is high it converted to carbonic acid ( H2CO3)
and pH become low. So there is a relation between pH and plankton.
When ammonia rise in pond, fish can not extract energy from feed
effectively. Ultimately fish going to comma and result in death.
