200 gallons of heavily automated jungle..........OK now you have my attention!!Thanks for the welcome! I appreciate it greatly and hope not to wear it out.
I keep one display tank only. This is 200 gallons, 72" long x 24" deep x 30" high. Aquascape is "jungle" style. Aquaristic methodology is high-light/high-tech, mildly acid soft-water. CO2 is maintained at 35 -40 ppm. Lighting is all LED. Substrate is inert gravel, but the ecosystem is now over five years old. This system is managed with Neptune Systems Apex Aquacontroller. It is heavily automated, and parameter monitoring is intensive. The above graph, for example, is ppm dissolved O2 plotted with light energy input over seven days, a typical week in the life of the jungle. I have been experimenting with a "continuous" water change protocol and I test frequently. I look forward to getting feedback on some ideas.
My formal education, and personal temperament, is scientific. This hobby touches on my interests in limnology, ecology, environmental engineering, and biogeochemistry. These are subjects I like to talk about. Also, I owe a good deal to the influence of Diana Walstad, Christel Kasselmann, and Karen Randall, from whom I have learned a lot over the years.
I like a populous, busy tank so stocking level is high. My preferences run to small loaches, corys, and tetras. It is a mixed community with both plants and fish from SE Asia and the Amazon basin. The keystone macrophyte population is Echinodorus, four "oriental" and one "ozelot", with extensive root systems.
