Rob1 There’s not much point in putting the values there unless you actually intend to put that water in your machine (don’t). Raise the alkalinity to something reasonable first. You’ll need to add 0.05g Sodium Bicarb a litre to get approx 40mg/l alkalinity…..good luck measuring that accurately so better adding to a larger quantity of water (e.g 5 litres) or make a concentrate.
Thanks Rob, firstly that “(don’t)” you add worries me because for the past two weeks that’s exactly what I’ve been doing, using the Zero Water instead of tap water assuming that was better, could you explain a little why it’s not, just so I understand.
OK, I’ll forget the spreadsheet, which’ll be much easier for me, and, instead, I’ll use the Zero Water with 0.05g/Ltr to get the 40mg/l you suggest. For the moment I’ll mix up 5 litres but could you explain how I make a concentrate and then use it, or point me to a resource that explains that? Google, thus far, hasn’t helped much in finding out how to do that.
Is doing a concentrate something like: mixing 0.5g to a litre (0.05g x 10) and then adding 100ml of that to a litre of water for use in espresso (1ltr ÷ 10)? My maths can be just atrocious so please correct me and suggest other measures if I’ve got it wrong or other concentrate amounts are better
Oh, and Sodium Bicarb and baking soda from my local supermarket are the same I imagine?
