I have a chlorine demand problem and had a Bioguard demand test done. Of course, test indicated that I need 22 lbs of Burnout 35 to break the demand. Burnout 35 is is Lithium Hypochlorite and about $8 a lb. If I do my calculations right, about 8 gallons of 12.5% liquid chlorine, 11 lbs of 73% calcium hypochlorite will give me the same result. Am I doing my calculations right?
