My low maintenance 75gal setup. 50% water changes every 6 months and closed top to prevent evaporation. Auto temp control with a 1/3hp chiller and 500w heater. 20w UV sterilizer. 4 fans built into the door in front of the chiller that come on with the chiller and allow me to cram it into the cabinet without overheating issues. Built in shelves for all the chems. Hose bib, hose rack and hose with quick disconnect and valve for quick water changes and no need to ever prime the system. Foil backed foam insulation under tank to prevent heat transfer between tank and cabinet. LED under cabinet lighting. All wood seamless with caulk and enamel. Brushed nickel hardware including an external towel rack for your wet hands. Trays on the doors for reagents and a pocket for paperwork. Auto controller for split photoperiod LED lighting. Only thing left is pumps to auto dose fertilizer.
