Not for me... and my hat's off to people trying to make that work. My evaporation rate is way to inconsistent for me to try that. All depends on the heat, and that varies significantly.

Seen those. Thanks! What I'm trying to do now is quite similar, except I've got a water pressure sensor at the bottom of a tube that passes through the bottom of the tank, rather than something over the top with an air pressure sensing on top. I suppose if I had set it up initially, I could get one of those bulkhead airline connectors to make that work. But messing with bulkheads now means tearing down the tank. Not an option for a year or so.

Not an option for me I'm afraid... sink's too high.

Thanks for the ideas though. Any ideas on how to get what I've got workind? How to get beyond that 10" of water state-cycling problem?
