氨氮

Beneficial bacteria, it is with the characteristic of ammonification, nitrification, denitrification, desulfidation and dephosphorylation, etc., its growth is very quickly, it has the good efficiency for degrading water quality factor, it can well reduce ammonia and nitrogen, degrade nitrite, increase the dissolved oxygen in water, activate water quality, rich water, purify water, adjust water color, increase the transparency of water, restrain the reproduction of pathogen, prevent diseases of fish, by using this product for long term, can restore the water-ecological balance destroyed by slathering disinfector, antibiotics, form the advantage community, improve the water quality quickly, keep the good water ecological balance, decrease the disk of breeding, increase the benefit of breeding.
