Thank you for posting this idea, it gives me other ideas for uses for autodosing dry ferts as mentioned above.
I do also have to agree with the above post about the design having a bit of danger to it by not being water proof with that much power and just hanging that close to the water. That said I don't think it would take much modification to splash shield it, hold it more securly a little further away from the water which would increase the safety factor signifigantly.
I also have to agree with it not being a cost savings unless you happen to have the extra mechanical timers laying around.
