Fire...I have not heard of this method of starting a fish quicker into hypo and I agree with reefer. IMHO..way too stressful on an already stressed fish. I usually have a new fish for 4-5 days in SG 1.025 before I start them into the gradual change over to hypo...unless, I clearly can see and 'white dots'.....then I would go right into my 2 day swing to hypo.
