How much isoproynal do you need to stop wfp system freezing?

i use just under 1/2 ltr in my 400 ltr tank and never froze , im not saying this is the correct amount .
there will most likely be more than 1/2 ltr in now as each time i fill my tank i add more ipa but theres times when ive still got water in my tank witch will all ready have ipa in it .
