Time-series for water quality parameters observed in the tanks subject to manipulation of microbial communities. Treatments include: the control (Ctrl), Lactic acid bacteria (LsB); Pseudomonas (PsB) and Environmental (EsB) bacterial strains. a–f Present the mean values and standard deviations of 3 replicates (p < 0.05) for TN, NH4+-N, DO, NO2−-N, NO3−-N, and COD concentrations respectively for samples obtained tested the Duncan multiple regression analysis tests in the months of July, August–September and October 2017
