Water quality is a measure of the quality of the fish breeding, many experienced farmers through the water quality can determine whether the sick fish, or whether the pond etc.. Method of purifying water in addition to the traditional method (water, aerator, lime), and a new method using water quality regulator: EM. EM bacteria contains a variety of functional microorganisms, can effectively decompose a variety of harmful substances. When the water quality fertilizer, turbidity, low transparency, the application amount of EM bacteria liquid, can keep the water clear, prevent water aging, promote the growth of phytoplankton and fish disease prevention. In addition, compared with traditional methods, the use of EM bacterial liquid can also bring rich natural food for fish.

The function of microbial EM bacteria can be decomposed plants, residual feed, excrement and garbage, the formation of fish and the nutrients required for its edible. The application of EM bacteria liquid, water plankton blooms, the water is green or brown green, the effect is very ideal.

EM broth into the water, the effect of population can kill or inhibit microbial pathogens and harmful substances, regulating the culture ecological environment, increase the dissolved oxygen (oxygen), promote the normal flora culture ecosystem in the beneficial algae growth and activation, maintain the ecological balance of aquaculture water; mix feed, direct enhancement fish disease resistance and absorption function, promote healthy growth. EM bacteria liquid in photosynthetic bacteria can use water, hydrogen sulfide, ammonium nitrite removal of organic acid, ammonia and amino acids with denitrification, thus enabling purification and excretion in the ponds and bait fish to reduce pollution and improve water quality.
