title: [Effects of Galla chinensis on bacteria and algae in pool water].
abstract: With experimental aquarium, this paper studied the effects of different concentration Galla chinensis on the bacteria and algae in pool water. The results showed that when treated for 72 h, there was a significant correlation (r = - 0.84349, P < 0.05) between the total number of bacteria and the concentration of G. chinensis. At the concentration of G. chinensis being higher than 3 mg x L(-1), the total number of bacteria was decreased by 96.2% averagely, and the proportion of Gram-negative bacteria decreased most. After 72 h, the total number of bacteria showed an increasing trend. Definite concentrations of G. Chinensis had a short-term inhibitory effect on the growth of algae. For fish-pond disinfection, the optimal concentration of G. Chinensis could be 3 mg x L(-1), and the optimal treating duration could be 72 h.
