I'm trying to find the original article where I first saw this.
The correct dosage is 1/2 Campden tablet in 10US gallons which assuming complete neutralisation raises the chloride level by something like 2ppm and the sulphate by 3ppm.
If there is less chloride then the bisulphite ion will react with the dissolved oxygen in teh water eliminating that.
The additions of sodium and/or potassium are similarly minute
I'll post the figures when I find them.
Interestingly I have been having a discussion with another brewer where the addition of 25-30ppm of Potassium metabisulphite to the mash helps prevent the oxidation of lipids during the mash. . . . which is a considerably higher level than adding 1/2 a campden tablet in 38L of water

I print a A4 copy of my recipe and put instructions on it as i am a huge fan of To Do lists. I then do my notes on the A4 sheet in pencil and keep the A4 sheet for reference. Its also good to post your brewday on here with photos as its entertaining, educational and you will have a e copy of what you did if the grey matter fails or the A4 sheet is lost.
