Nitrogen and mineral concentrations of the nutrient solution in mg L-1 at the beginning of the experiment used for control and both aquaponic treatments.

The data represent the mean concentrations of nutrients in the three different nutrient solutions ± standard deviation measured after the nutrient solutions were mixed and completely prepared before the experiment started. The control was prepared with fresh and rain water (50:50, v/v), APunt and APdis were prepared with fish water. While APunt was untreated, APdis was disinfected. The data was compared and tested using univariate ANOVA and post hoc tests Tukey-HSD test or using Kruskal-Wallis (Cu) and Dunn-Bonferroni (Fe, Mo, B) test. Different superscript small letters indicate significant differences between the treatments (p
