i have seen an add for a wi-fi feeder/level tester/webcam system so you can feed from afar and when the levels get high you phone into your friend/famaly member/ w/e instructions to keep it under control untill you get back
Actually, I am thinking of something that is somewhat automated, not quite the way you described... Not sure if it will work since I never worked with overflow system before...
Does anyone here thinks I can modify the following to drain water from the tank if it reaches beyond certain levels?

The idea here is to setup two big plastic garbage can next to the tanks. One is empty, the other contains full of conditioned water at room temperature. Setup one water pump at low flow and use a timer to pump conditioned water into the tank using timer. And the overflow device above will take care of excess water into the empty garbage container.
Haha I feel this is a recepe for disaster... :devil:
