    Hi there,

    My pattern is to use HCl and H2SO4 to reduced alkalinity and balance ions in a single step.

    At present I do it with a pen and paper!

    Is it possible to do this using the advanced water calculator - or can I only add one acid to the mash?

    Thanks

    We currently only have one entry for acid in the mash:

    However, if you know the combined strength, you can do it by strength and then add it to your recipe 'by hand':

    It's not ideal for your use, but I don't think that it's common to use more than one acid in the mash.

    Thanks for that.

    Here in Norfolk UK, the starting alkalinity is 230ppm, so we are always having to reduce it!

    CRS is fine, but unsophisticated in its impact on ion balance, requiring additional minerals that can lead to going too high on some levels.

    Effectively what I am doing is 'blending' my own version of CRS for different beer types.

    My practice is to use 2M HCl and 1M H2SO4 so that the alkalinity calculations are the same (1ml/L for 100ppm)

    I guess a pen and paper will continue to be fine!

    Cheers

    MArtin .

    We can add a note in when we're working on the water chemistry overhaul and see if this can be added.

    Interesting approach to adding anions without adding the metals.
