Additional Information The system was set up in December 2019 and I plan to keep it running in its current form for a few years, although I'm sure the planting may evolve over time.
The aquatic section is currently run like a high energy aquarium, with daily lean fertilization, pressurized CO2, and 50% water changed weekly using remineralized RO water.
The lights over the water is on for 8 hours a day, and over the land section 10 hours a day.
I designed the overflow box and weir using clear glass and acrylic respectively, so that it would mostly disappear in front of the back lit background.
Water is pumped from the sump to the land section using multiple thin pipes to keep the Amazonia soil and epiphytic plants above the water line moist, as well as to keep the fogger's reservoir (placed in the back corner) filled with water. The fogger activates once an hour for 15 minutes, or whenever the local relative humidity of the land section drops below 70%. I hand mist all plants twice a week with RO water.
