sorry, i have been using it in my larger fermenter but you are right, i went back and listened, it was exactly 1 floz of bleach, and 1 floz of white vinegar to 5 gallons.
therefore 28-30ml each of bleach and vinegar to 18.9 litres of water..
i will correct my orig post!!
But also they went onto to say that gives you 80ppm and depending on the PH you could run in alot lower.
