Schematic illustration of the experimental design in the FishGlassHouse with aquaculture section: intensive aquaculture unit (IAU) with nine fish tanks (F1-9), sedimenter (Se-I), sump (S-I) and trickling filter (TF-I); extensive aquaculture unit (EAU) with nine fish tanks (F1-9), sedimenter (Se-E), sump (S-E), and trickling filter (TF-E); water management system with tanks supplying waste water to hydroponics (WT-I-1 of IAU; WT-E-1 of EAU), and discharging waste water tanks (WT-I-2 of IAU; WT-E-2 of EAU); hydroponics unit with aquaculture effluent tanks for the IAU (AET-I) and EAU (AET-E), dissolved fertiliser liquid tank for control (Control) and nine ebb-and-flood planting tables corresponding to aquaculture effluent and control fertiliser tanks (T-EAU-1/3, T-C-1/3, T-IAU-1/3), substrate variants were symbolised from Trial I: with control as S1 and "Einheitserde" as E, and Trial II: control (S2) and “Humicacid Fiber-Substrate” as HFS with used pot numbers (11) for analytics in brackets. Fluid supply pipes are shown solid and return pipes are drawn dashed.
