Ill try to answer several questions with one post. I envision a system that eventually can be monitored 24 hours a day an almost in increment of time at various points in the system. The data would be collected automatically and written to either an Access or SQL datatable(s). This data could then be cross referenced with data collected on feeding, planting, etc to develop some trend tables and to track and plot changes in the system versus external changes. (type and amount of fish food, lighting, temp, etc).

Also, as an MBA, I am always interested in doing various types of cost analysis and ROI analysis on any system in an attempt to maximize output. I know it may seem like overkill, but it is the kind of data that I love working with and if I can integrate it into my aquaponics projects it just makes it more interesting.
