Factors that influence water quality

     Fotosistesis
     temperature
     Dissolved oxygen
     Planton
     Water pH
     Fish Waste
     ammonia


Many water quality parameters such as DO, CO2, pH round, fish waste is controlled by the reaction carried out by phytoplankton photosynthesis. In summary, the process of photosynthesis is carried out by phytoplankton that use sunlight to convert CO2 into food (carbohydrates) and release O2.

temperature

Is one important factor to fish. Fish have a body temperature equal to the temperature environment (water). Temperature will affect: -
  

     Activities (Process excretion)
     movement
     food
     Growth And Breeding All Species


The ideal temperature between 25 º C ~ 32 º C. Temperature also plays a role in the process of "thermal stratification".





Dissolved oxygen

Just like humans, fish need O2 for the process of respiration (breathing). Amount of O2 needed by fish is dependent on the size, feed rate, activity level and temperature. To obtain a high growth rate of fish, fish should be bred at the optimal levels of O2. Low O2 content less than 5 ppm / l will cause the fish to feel depressed. At levels less than 2 ppm / l may cause fish kills.
