Are you running the bubblemaster in both pans? How much does it increase your boil rate by? I've thought off/on about building one, but don't want to listen to a wet/dry vac outside the sugarhouse, and I like making dark syrup. I thought about tapping off the high pressure blower that feeds the evaporator, but that air's not filtered, and I don't know if I'd be robbing the evap. of too much air.
