I'm interested in using computers to control the environment for growing plants etc. The problem is that most systems don't actually make life easier, unless you are growing on a massive scale. For hobbyists the extra work usually isn't worth it. You end up replacing one boring chore with another. Also, because these systems are used for education, for business, and for research, the manufacturers are inclined to overcharge excessively.
So yes in theory, I would like to see a range of data acquisition/environmental control systems specifically for aquatics. In practice, I'd rather not have the luxury if it comes at considerable expense, and needs constant care and attention to work.
If someone invents a mass spectrometer that sits in the aquarium, and never needs calibration, I'd be all for it.
