Nice setup. I'm no bong expert, but I'm suprised that you don't incorporate some sort of liquid level switch in the bong bucket to give an alarm if the level gets low, and shut down if it gets dangerously low.

I've been thinking about how to do that on my rad cooled system, which is a challenge because most switches won't fit in my res. I would think your bucket is big enough to make that much easier.

Of course the ultimate might be to plumb the bucket into the house plumbing using some version of a toilet tank fill valve so that the level maintainance would be automated.
