Is there a fish tank computers?

Icthyology is certainly a science. There are very real scientific, indeed technological problems involving water volume, salinity ( measured indirectly with specific gravity meters) water temperature for different species, and even feeding that would seem to call out for if not computerization proper, at least automation. Almost certainly the big aquariums like New York Aquarium have ( management systems) of this type, a shift supervisor would stand watch behind a console not too different than that in a power house and have all the ready facts at hand. All of these involve quantities and in effect math, so computer oversight would be negotiable ( like Photography where all the basic factors, Range, Focusing stop ( F-stop or aperture) , shutter speed, film speed, are expressed numerically, it calls out for well, first of all the photometer which is an Excellent example of an analog c omputer. I am not aware or any simplified aquarium computers of , say the circular slide-rule variety ( again, akin to a photometer"s EV settings) but the idea is long overdue. Apply some computer science to the fish tank!
