description Purpose. To investigate the effect of the bacterial preparation "Komplezim", which is recommended for the prevention of mass reproduction of blue-green algae through algocoenosis correction, water cleaning and sanitary regime restoration, for the biological balance and self-purification of natural and farmed fish ponds of all sizes exposed to artificial or natural pollution. Methodology. The studies were carried out during 30 days in a 0.01 hectare pond with a depth of 1.0–1.5 m. The doses of the bacterial preparation "Komplezim" in the form of a solution were applied over the water surface of the experimental pond. The conventional techniques of hydrochemistry and hydrobiology were used to perform hydroecological studies. Findings. The study results showed that after the exposure of the bacterial preparation "Komplezim", pH level of water and oxidation rates were within the acceptable limits. Permanganate and dichromate oxidation decreased in the same manner in the middle and end of the experiment compared to initial values. Calcium, magnesium, and sulfate levels were lower compared to control values. This effect can be explained by the fact that bacteria from the “Komplezim” composition in aquatic medium started intensive metabolizing the products of organic decomposition enriched in calcium, magnesium and sulfates. The consequence of the application of "Komplezim" was an increase in the concentration of organic chlorides simultaneously with nitrites. The obtained results indicate that bacteria strains included in the “Komplezim” composition inhibit the processes of cyanobacteria reproduction by algocenosis correction and contributes to the optimization of hydrochemical conditions for pond fish rearing. Originality. The effect of the bacterial preparation "Komplezim" on the reproduction of blue-green algae and hydro-chemical composition of the water has been investigated for the first time. Practical value. Application of the bacterial preparation "Komplezim" results in the balanced development of blue-green bacteria, which are developed in large amounts in intact water bodies that largely resolves operational and environmental problems and allows achieving accelerated processes of the purification of water bodies.
