OK...I just found and online conversion chart and came up with a dose of 4.7cc per gallon instead of the 9.5 (?) that was just recommended in another thread. Am I doing this wrong? THis is for the 5-7 day treatment. It says 16oz per 100 gallons on the bottle, which I made into .16oz per gallon...that converts to 4.7cc's or ml's (I think.) Anyone recently made up a batch?
