Petsmart has containers for feeding and watering cats that allows water to flow down from a tank once the normal level of the water decreases, this happens because air bubbles get into the tank and rise to the top thus pushing the water down, but only enough until the air stops entering.
I figured i could attach a seperate tank to the side of the bong and run a hose down to where the normal water level is, once the water level in the bong gets below this point, the second tank will atomatically refill it. No electronic hassels, no expensive valves.

Yes that would work. But three issues:
1) Tank has to be entirely above minimum water level line
2) Tank must have holes in it below water level
3) Tank must be airtight yet refillable. An air leak could produce a most unsightly overflow
