I use ascorbic acid (vitamin C) to remove chlorine and chloramines from my tap water. By-product is ammonia which is a yeast nutrient.
I am no water chemist and rely on https://sites.google.com/site/brunwater/ to set my brew water chemistry.
Only need about 25mg of pure ascorbic acid for 34...
Might want to check the formulas on mine. Looks like the Rye ($54) hasn't been included in the total. Otherwise all good to go.
Happy to help out on distribution day. Like your work Donske!
