That's cool that you can pull that off with your doser. I evaporate about 8 gallons every 3 days so I could not imagine trying to run that much volume through the doser. That certainly would shorten the life of the motor dramatically. Also, the amount of evaporation varies from day to day. I would find that difficult to manage with a doser.
