Might have to get a gallon and try it. Yeah... I've learned. Best results with Chauvets own brand is only Chauvet fluid. I've used other things (and some good fluids, too!) in some Chauvet foggers and it's been a mess. Residue all over the floor, the unit itself, clogs etc. I've had Chauvet reps say you can put other stuff like Froggy's in the Geyser but, I'm not about to risk it.
